Inc. 675 Mass Ave, Cambridge, MA 02139, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR PDP.LICENSE, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. Copyright (C) 19yy This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details. You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA. Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) 19yy name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker. , 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License. pdp-0.14.1/Makefile000066400000000000000000000042411225432502200140160ustar00rootroot00000000000000include Makefile.config # hc ? #ifeq ($(OS_NAME),darwin) #all: darwin #else #all: linux #endif all: $(PDP_TARGET) everything: all make -C opengl make -C scaf pdp_all: make -C system make -C puredata make -C modules darwin: pdp_all rm -f pdp.pd_darwin $(CC) -o pdp.pd_darwin modules/*/*.o system/pdp.o system/*/*.o puredata/*.o $(PDP_LIBS) -bundle -undefined dynamic_lookup -twolevel_namespace -bundle_loader $(PD_EXECUTABLE) linux: pdp_all rm -f pdp.pd_linux $(CC) -rdynamic -shared -o pdp.pd_linux modules/*/*.o system/pdp.o system/*/*.o puredata/*.o $(PDP_LIBS) linux_mmx: linux linux_gcc_mmx: linux buildclean: make -C include clean make -C system clean make -C puredata clean make -C modules clean backupclean: rm -f *~ */*~ */*/*~ clean: buildclean backupclean rm -f pdp.pd_linux distroclean: buildclean make -C scaf clean make -C opengl clean mrproper: clean distroclean make -C scaf mrproper rm -rf configure rm -rf config.log rm -rf config.status rm -rf autom4te.cache #this needs to stay in to keep the makefiles working #rm -rf Makefile.config tags: etags --language=auto include/*.h system/*.c system/mmx/*.s system/*/*.c puredata/*.c \ modules/*/*.c scaf/*/*.c scaf/*/*.s opengl/*/*.c tagsclean: rm -f TAGS install: all #check if pd is installed. if this fails make install will stop here. test -d $(prefix)/lib/pd install -d $(prefix)/lib/pd/extra install -m 755 $(PDP_LIBRARY_NAME) $(prefix)/lib/pd/extra install -m 755 -d $(prefix)/include/pdp install -m 644 include/*.h $(prefix)/include/pdp install -m 644 abstractions/*.pd $(prefix)/lib/pd/extra install -m 644 doc/objects/*.pd $(prefix)/lib/pd/doc/5.reference install -m 755 -d $(prefix)/lib/pd/doc/pdp install -m 755 -d $(prefix)/lib/pd/doc/pdp/introduction install -m 755 -d $(prefix)/lib/pd/doc/pdp/examples install -m 644 doc/reference.txt $(prefix)/lib/pd/doc/pdp install -m 644 doc/introduction/*.pd $(prefix)/lib/pd/doc/pdp/introduction install -m 644 doc/examples/*.pd $(prefix)/lib/pd/doc/pdp/examples install -m 755 bin/pdp-config $(prefix)/bin snapshot: bin/snapshot -d darcs release: bin/snapshot `bin/release-version` @echo bump PDP_VERSION in configure.ac! pdp-0.14.1/Makefile.config.in000066400000000000000000000030421225432502200156650ustar00rootroot00000000000000# if configure can't find the m_pd.h header # specify pd's include path here and ignore the warning # #PD_CPPFLAGS=-I/path_to_pd_dir/src #PD_EXECUTABLE=/path_to_pd_dir/bin/pd PD_CPPFLAGS=@PD_CPPFLAGS@ PD_EXECUTABLE=@PD_EXECUTABLE@ PDP_CFLAGS=@PDP_CFLAGS@ # these are reused in opengl module prefix=@prefix@ PDP_VERSION=@PDP_VERSION@ PDP_TARGET=@PDP_TARGET@ PDP_LIBRARY_NAME = @PDP_LIBRARY_NAME@ PDP_EXTRA_CPPFLAGS = @PDP_EXTRA_CPPFLAGS@ PDP_EXTRA_CFLAGS = @PDP_EXTRA_CFLAGS@ SDL_FLAGS = -D_REENTRANT # optional objects PDP_OPTMOD = @PDP_OPTMOD@ PDP_X11MOD = @PDP_X11MOD@ PDP_PDMOD = @PDP_PDMOD@ PDP_OPTTYPES = @PDP_OPTTYPES@ PDP_MATRIX_BASIC = @PDP_MATRIX_BASIC@ PDP_IMAGE_BASIC = @PDP_IMAGE_BASIC@ PDP_IMAGE_SPECIAL = @PDP_IMAGE_SPECIAL@ ZL_OPTMOD = @ZL_OPTMOD@ PDP_CPPFLAGS = -I. -I../../system -I/usr/X11R6/include -I../include -I../../include $(PD_CPPFLAGS) $(PDP_EXTRA_CPPFLAGS) -DPDP_TARGET=$(PDP_TARGET) PDP_LIBS = @LIBS@ PDP_AFLAGS = #--gstabs PDP_CFLAGS += $(SDL_CFLAGS) $(PDP_EXTRA_CFLAGS) -DPDP_VERSION=\"$(PDP_VERSION)\" ifeq ($(shell uname -s),Darwin) PDP_CFLAGS += -fnested-functions endif #PDP_CFLAGS = -DPD -O2 -funroll-loops -fomit-frame-pointer -ffast-math \ # -Wall -W -Wstrict-prototypes \ # -Wno-unused -Wno-parentheses -Wno-switch -DPDP_VERSION=\"$(PDP_VERSION)\" \ # -g $(SDL_CFLAGS) $(PDP_EXTRA_CFLAGS) # -Werror # -Wshadow # compiler and assembler #CC = gcc-3.2 #CC = gcc #AS = as CC = @CC@ # build rules .c.o: $(CC) $(PDP_CFLAGS) $(PDP_CPPFLAGS) -o $*.o -c $*.c .s.o: $(AS) -o $*.o $*.s $(PDP_AFLAGS) pdp-0.14.1/README000066400000000000000000000237711225432502200132470ustar00rootroot00000000000000PDP - Pure Data Packet v0.12.7 a packet processing library for pure data Copyright (c) by Tom Schouten This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

(see doc/reference.txt) Optional features * cellular automata simulator and effects processor with built in forth extension language (only for mmx) * opengl 3d processing (gem like, but built around packets) See the README files in the scaf/ and opengl/ dirs for more info on the extension libraries. Requirements: * pd * linux * libgsl * a video4linux device for video input. special support for philips webcam included. * libquicktime (not quicktime4linux!) for quicktime playback. * libpng for png image loading/saving * an X display with XVideo extension, glx or SDL for video display. Documentation: When you use "make install" to install pd, all docs will be in the pd doc directory. Right click on an object and select help for a help patch. The pdp directory in pd's doc contains a reference.txt file which lists all objects and abstractions and an introduction and example section. NOTE: all help patches use a pdp_help_input and pdp_help_output abstraction. you can edit these to choose which input or output object you want for the help patches. Building: ./configure make Options for configure: --enable-mmx compile with mmx support --enable-pwc force pdp_v4l to use philips web cam If pd is not installed in /usr/local you'll have to specify the prefix on the configure command line with ./configure --prefix=/prefix type make install To install pdp in $prefix/lib/pd: the library in externs/ the abstractions in extra/ and the documentation in doc/5.reference and doc/pdp You can also try the "buildall" script. This will configure, build and install the whole distribution. It works for intel/mmx. NOTE: If you're not using the standard pd install location, and have everything in a single tree, just untar pdp next to the pd source tree, or set the prefix dir to the location of the pd source. Bugs: See the TODO file. Apart from the few items listed on top of this file, pdp is fairly stable: i am unaware of crash bugs. If you encounter a crash please consider sending a bug report. PiDiP Is Definitely In Pieces Have a look at Yves Degoyon's PiDiP library, the must have addition to the basic pdp library. It contains a lot of extra effects (from EffecTV and FreeJ), a quicktime recording object, streaming modules, ascii art objects ... (the list is growing rapidly ;) Yves also did a gem2pd and a pdp2gem object to connect pdp and gem together. http://ydegoyon.free.fr/ Acknowledgements PDP is no longer a one man show. Many thanks to the people who directly or indirectly contributed to this project. Either by writing a giant extension lib (thanks Yves) or by contributing code snippets (Thanks Martin, CK), or by giving mental support, feedback, bug reports and ideas. I also wish to thank the GEM crew. This project borrows a lot of ideas and some code from the GEM project. And while i'm at it, i wish to thank everyone who contributed code to the PD project as a whole and the people that are very helpful at answering questions on the mailing list. Last but not least i wish to thank Miller for making the PD project open source. If that didn't happen i wouldn't know what i'd be doing now :) Some Remarks: * New versions of this package can be found at http://zwizwa.be/pd/pdp Experimental relases are in the subdirectory test/ But best to track the darcs archive at http://zwizwa.be/darcs/pdp-12 * If you have libquicktime and quicktime4linux installed, this can give problems with the configure script. Consider removing quicktime4linux. (libquicktime is a drop-in replacement). * The modules that depend on system libraries only get compiled when the configure script can locate them. If compilation or linking fails please let me know. * Packets can be processed in a low priority thread with a dropping mechanism to prevent overload or audio drops, or they can be processed in the main pd thread. This can be set/unset by sending a "thread x" message to pdp_control. Processing in pdp thread is off by default. Use the pd thread for rock solid video timing. Increase the audio latency to avoid dropouts. If you want low audio latency, and don't care about a dropped video frame here and there, switch on the pdp thread. Note that when using the pdp thread, the control flow is no longer depth first. Additinal delays will be introduced. * Pdp runs on osx, using an x server (apple or fink) and libquickime (fink). pdp_xv does not work yet. Once apple includes xv support in their x server, it should. Until then, use pdp_glx for output. * Some quicktime remarks: pdp_qt~ is still a bit experimental, you might try pdp_yqt in yves' lib to see if it works better for you. Also, it seems that libquicktime does not work with compressed headers. The suggested codec is jpeg (photo) and uncompressed audio with the same samplerate as the one pd is using. You can use other codecs, but i've found this one to perform the best. (hint: compile libquicktime with mmx jpeg support) Try to avoid the mpga codec. It is haunted. * The reason i use YV12 and not RGB is simple: it's faster, and for linear operations it doesn't make much difference. Most camera's and codecs use a luma/chroma system, and most video cards support hardware accellerated display. Note that in YUV, the u (Cb) and v (Cr) components can be negative, so saturation after multiplication with a positive (or negative) value produces not only black and white, but also red, green, blue and their complements. In short, in YUV, nonlinear operations have a different effect than in RGB. Another thing: all the spatial operations are not implemented "correctly" because of the subsampling involved.The image packets are 16bit/component planar. This is to simplify the mmx code and to have a little more headroom and precision for processing. * Since version 0.11 there is a type system used for identifying a packet type and performing type conversion. A type is represented by a symbol, with subtypes separated by the "/" character. I.e. "image/grey/320x240" is a grey 16 bit/component image with dimensions 320 by 240. For conversions a wildcard can be specified. I.e. "image/*/*" which matches image type packets with all encodings and dimensions. * Since version 0.12 there are 2 different image data types: "image/*/*" and "bitmap/*/*". The image type is the native 16 bit/component pdp type. It supports the subtypes "image/grey/*": one channel grey scale images, "image/YCrCb/*": luma/chroma packets with subsampled chroma planes and "image/multi/*": a multi channel planar format (i.e. to store 3 or 4 channel rgb or rgba data). Almost all processors use this data type. The bitmap type is an intermediate type which can contain standard fourcc encoded 8 bit/component images i.e. "bitmap/rgb/*", "bitmap/yv12/*", "bitmap/grey/*". Currently no processors support this type natively, so you have to use pdp_convert to convert them to "image/*/*". * Writing new objects is not much different than normal pd externs. Pdp just adds some functions to the pd kernel for package allocation, manipulation and communication. The api is very raw to keep it as simple as possible. Since 0.10 there is a pdp_base object you can derive your objects from. Have a look at pdp_add, pdp_gain and pdp_noise to see how it works. There is not much documentation, but i do my best to keep things clean so the code and the header files should get you started. You can always just send me an email for info, or ask on the pd-dev list. Since version 0.12 there is a simple forth scripting language in pdp. This is far from finished, but it should make pdp programming a lot easier. * Philips webcam detection is now automatic. However this requires a fairly recent kernel (one which includes the pwc driver version 8.6 or higher). If you have a pwc and pdp_v4l does not display a "pwc detected" message, you can conifigure with --enable-pwc. This forces pdp_v4l to use the pwc api extensions.

Adapted from the version 0.12.4 released on 09-Jul-2004. As you might know, i started working on Packet Forth about two years ago. This has shifted my opinion as to what PDP should be quite a bit. In order not to annoy people using the old PDP with my new and exciting insights about forth, I declare this version to be the `stable' PDP 12. The DEC PDP 13 never existed, so this might have been a sign... For people interested in packet forth, check http://zwizwa.be/packetforth for more information. Stable PDP might include some additions from PF later on, but main focus right now is stability.

(here yuv or YCrCb). since legal colours can be both positive and negative \, the analogy with audio signals is easily drawn. this network can be seen as a nonlinear feedback delay network. (nonlinear because of the saturating gain). the image delay line can be seen as a parallel delay line \, one for each pixel. coupling between the delays is done using a spatial blur effect. the additional temporal filtering isn't necessary \, but it produces a nice additional effect.;

FIXME: This is probably a bit out of date.

PDP Developer Documentation

Introduction

There is not yet much developer information, partly because pdp is not that big and since the goals are not completely clear yet, a lot will probably change on the inside in the future. I believe it is not too hard to figure out how it works, once you get started somewhere. This document is a minimalistic attempt to provide that starting point. For full prototypes see the header files. I suggest you have a look at the pdp_base base class, and some simple modules: pdp_add, pdp_noise and pdp_gain for examples.

PDP architecture

Architecture is a big word, but pdp is organized as modules. A packet pool module (a reuse pool memory manager), a packet class, a processing queue module, a high level type conversion module, an image packet class, and some low level modules for image type conversion, image resampling and all sorts of other image processing. Besides that there are 2 extension libraries: pdp_scaf, a cellular automata extension and pdp_opengl, a 3d rendering extension. These are separate because of portability issues. The different pdp_* externs in the main pdp library use the core modules' functionality to minimize code duplication. I'm relatively happy with how it fits together, but some things need to change for future plans. Most objects are written in the object oriented c style of pd. To prevent namespace conflicts, (almost) all routines start with the pdp_ prefix. The second name is the name of the object or module they belong to. The first argument is always a pointer to an object or an integer (for packets).

PD ties

PDP is written as an extension for PD. One of the goals of pdp is to evolve to a separate library that can be reused in other software. The architecture will be split into two parts. A pd-independent part (the packet classes, the packet pool, the type conversion system and the forth system) and a part with pd specific stuff (the process queue and interfaces to the pd system like the base classes and the pd communication protocol). In order to do this the packet class will probably evolve to a proper object model, supporting run time attribute binding (inspired by the python object model).

There are some things that put a stamp on the current pdp design. Most importantly pd's processor object model and communication protocol. (i.e. the fact that pd only supports unidirectional messaging creates the awkward concept of a "passing packet" to eliminate excessive data copying.)

In pd, the pdp messaging protocol is implemented as pd messages. The protocol is however 3 phase. With a read only register phase, a read/write register phase and a process phase. This functionality is part of the base class or the forth processor object. The dpd protocol is entirely different, and is used in the opengl library. It is not based on parallel dataflow but serial context passing.

Packets

PDP introduces a new atom: the data packet. This can contain all kinds of data. Images (16bit/8bit), cellular automata (1bit), matrices (real/complex float/double), opengl textures and 3d rendering contexts. Packets are stored in a pool to ensure fast reuse, and to enable sharing. The paradigm is centered around a combination of an object oriented approach and a dataflow approach.

The methods operating on packets (pdp_packet_*) are mainly for administrative purposes: memory management (construction, registering, copying) and getting or setting info.

All processing is done in the pd modules. Processors can be defined using the forth scripting language, but this is still experimental. The forth system can be accessed from the guile library.

There is a central mechanism for packet type conversion. This is to facilitate the combination of different media types. Whenever a packet class is constructed (i.e. in an extension library), a number of conversion routines should be defined to convert the added type to one or some of the main pdp types.

PDP API Overview

The pdp public api contains only a single class: the packet. (The internal api has more classes, that can be used too if necessary, but i won't document them.) A packet is a class in pdp. The table below lists the supported methods. The first argument of a call is a packet id.
pdp_packet_*
new construct a raw packet (depreciated)
new_* construct packet of specific type/subtype/...
mark_unused release
mark_passing conditional release (release on first copy ro/rw)
copy_ro readonly (shared) copy
copy_rw private copy
clone_rw private copy (copies only meta data, not the content)
header get the raw header (t_pdp *)
data get the raw data (void *)
pass_if_valid send a packet to pd outlet, if it is valid, and mark unused
replace_if_valid delete packet and replace with new one, if new is valid
copy_ro_or_drop copy readonly, or don't copy if dest slot is full + send drop notify
copy_rw_or_drop same, but private copy
get_description retrieve type info
convert_ro same as copy_ro, but with an automatic conversion matching a type template
convert_rw same as convert_ro, but producing a private copy

The pool object methods. All the packets are stored in a central packet pool.
pdp_pool_*
collect_garbage manually free all unused resources in packet pool

The process queue object methods. PDP supports a separate processing thread.
pdp_queue_*
add add a process method + callback
finish wait until a specific task is done
wait wait until processing queue is done

The control methods. General pdp control messages.
pdp_control_*
notify_drop notify that a packet has been dropped

The type mediator methods.
pdp_type_*
description_match check if two type templates match
register_conversion register a type conversion program

NOTE: it is advised to derive your module from the pdp base class defined in pdp_base.h instead of communicating directly with the pdp core

pdp_base class

If you want to write a pdp extern, you can derive it from the pdp_base class, instead of t_object. This class abstracts a lot of the hassle of writing ordinary (inplace) packet processors. The base allows you to register process callbacks. There are 3 kinds of callbacks: preproc, process and postproc. The preproc method is called inside the pd thread. This can be used to setup some things that can only be done inside the pd thread. The process method should do most of the work, and is called from the pdp processing thread if it is enabled, after the preproc method is finished. You can't use most of pd's calls in this method. The postproc method is called from the pd thread after the process method is finished, and can be used to send data to pd outlets. Simple packet processors only need the process method (packet input/output is handled by the pdp_base class).

pdp_imageproc_* modules

Most of the image processing code is organized as planar 16 bit signed processors. This is crude and oversimplified, but it helps to keep the code size small and fast at the same time (platform dependent assembly code is reduced to a bare minimum). These routines can be used to build higher level image processing objects that are more (cache) efficient than an abstraction using separate pdp modules. If you plan to write your own image processing routines, you can use the pdp_imageproc_dispatch_ routine to support all 16bit image types at once (greyscale, subsampled YCrCb, multichannel planar). This requires you write the image processing routine as a planar (greyscale) processor using the pdp_imageproc_ interface. (see pdp_imageproc.h)

pdp_llconv call

Low level image conversion routines. (operating on raw data buffers). You probably won't need this, since the high level type conversion (pdp_packet_convert_ro/rw) covers most of its functionality.

Pure Data Packet

Introduction

PDP is an extension library for Pure Data, aimed at providing video and other media processing fuctionality. That's still it's main purpose, but as of version 0.13, there is more. PDP turned into a tool for writing PDP. See the section on Packet Forth.

PDP runs on Linux and OSX. The OSX version depends on Fink.

PDP's focus is on images and video, but there is no reason it should stay like that. There is support for matrix processing, 1D and 2D binary cellular automata, opengl rendering (like Gem), scheme scripting (guile), ascii packets, bit grids, ...

For more image processing objects, streaming objects and a collection of very useful additions to the bare bones PDP functionality, have a look at Yves Degoyon's PiDiP library.

Since version 0.13.x, which is a merger between stable (0.12.x) and packet forth, PDP has been split up into 3 parts:

  • libtile - A lowlevel library for platform specific (integer, mmx, altivec) image processing operations and cache optimizations.
  • libpdp - The packet managing library + pf scripting language.
  • pdp - This is the stable pdp 0.12.x with support for packet forth.

    PDP for Pure Data

     This is considered to be the stable part of pdp. It has been stable since 0.12.x It has it's bugs & drawbacks & oversimplifications but will mostly stay like it is. It is optimized for intel/mmx and uses a 16bit signed yuv format ideal for real time video processing, mixing, blending and feedback. The pf layer is accessible from pd/pdp. The result of this is that you can write pdp objects in pf, or directly map pf operations to pdp objects. A 'getting started' documentation for pd/pdp/pidip is being worked on. Until then you can have a look at the 'pdp' subdirectory in pd's 'Pure Documentation'. Most objects are documented with pd style help patches accessible by right clicking on an object. The place to send questions is the pd mailing list. Bugreports can be sent to the pd list or me: pdp TA zzz TOD kotnet TOD org .

    Packet Forth

     The libpdp library is a C support library for media processing. It implements a mime-like media type system (packets), type conversion and packet operations, interface logic to connect pf to other applications, and other things you might need to write small 'scratch' media applications. All operations are implemented as extensions to a forth-like glue language called Packet Forth. For more information on this see the documentation in the libpdp distribution, or the mailing list archives.

    CVS

     The latest stable pdp release is 0.12.4. Because 0.13.x is still in a flux, the preferred way of accessing the code is CVS. You can access the modules in this way:

    export CVSROOT=:pserver:anonymous@zwizwa.fartit.com:/usr/local/cvsroot
    cvs login
    cvs co libtile
    cvs co libpdp
    cvs co pdp

    To update, simply cd to each of the 3 directories, and type cvs update -d.

    When extracting from cvs, you need to run the ./bootstrap script to create the configure scripts and build and install the packages in the order above. In order to compile pdp with libpdp (pf) support, you need to add a --enable-pf option when invoking pdp's configure script.

Using [pdp_rawout] and [pdp_rawout~] it is possible to dump video and audio streams directly to harddisk using the minimal amount of cpu time. There they can be picked up later by tools like mencoder and ffmpeg. ( For playback, pdp supports only libquicktime, which is, next to mjpegtools, a good solution for frame-based seekable video files. Since version 0.9.4 libquicktime supposedly supports AVI playback and record. Streaming playback and more efficient block codecs can be supported externally using [pdp_rawin] ) FFMPEG ------ FFMPEG is the 'industry standard' for open source video encoding. Its core components are libavcodec and libavformat, which implement the coder/decoder and container format handling. The latter two are used in a lot of other projects, like MPlayer and libquicktime. Send a video stream through [pdp_convert bitmap/i420/*] then stream it to disk using [pdp_rawout /tmp/video.i420] while you are performing. You can convert it to divx avi using ffmpeg -an -r 25 -s 320x240 -f rawvideo -i video.i420 video.avi To include audio, use [pdp_rawout~ 2 /tmp/audio.s16] to stream audio to disk. You can convert it with ffmpeg using ffmpeg -ar 44100 -ac 2 -f s16le -i audio.s16 audio.mp3 Doing both at the same time: ffmpeg -r 25 -s 320x240 -f rawvideo -i video.i420 -ar 44100 -ac 2 -f s16le -i audio.s16 -vcodec mjpeg -b 3000 clip.avi Note: i didn't figure out how to make ffmpeg read yv12 encoded files. However, pdp supports the bitmap/i420/* format. The latter is also the data format used in the yuv4mpeg protocol from the mjpeg tools. Codecs and Bitrates ------------------- The preferred codec to use during the editing stage is motion JPEG. If you have the space, use raw files, but i haven't figured out how to make them portable. The most portable mjpeg format seems to be wrapped in a mov. This is the format used in cinelerra. Uncompressed 320x240x25 yv12/i420 is 2.88 mbyte/sec A decent mjpeg compresion rate is 4:1, giving 720 kbyte/sec = 5760 kbit/sec with practically no loss of quality. 3000 and 2000 kbps are still acceptable. Sometimes it might be interesting to create DV files. These have a tighter binding to TV norms PAL and NTSC, and seem to be a standard at this moment. DV gives about 13gig/hour or 3 mbyte/sec. The actual rate is 5:1 compression at 25 Mbps (video only). Adding audio, timecode, etc.. comes to about 29 Mbps. (TODO: how to create DV files) The preferred distribution codec is either DIVX or H.264 (don't confuse with H.263 which is aimed at low bitrate video conferencing) A/V sync -------- The key to A/V sync is the observation that the ratio between audio and video frequency (samplerate and framerate), is a _rational_ one. This enables to have perfect sync: there are no roundoff errors since the relation between audio and video sample times can be computed exactly. The object [pdp_metro~] can be used to produce a locked video clock, given a rational framerate. It can produce a video clock that is compatible with standard A/V rates. For example the awkward 29.97Hz video rate is exactly supported as 29970/1000. Note that the 44.1kHz audio rate does not yield simple fractions for standard NTSC and PAL/SECAM framerates. I.e. in DV you have to use 48kHz. Enabling arbitrary long buffering (bufsize -1) in [pdp_rawout] and using [pdp_metro~] with the correct sample rate and video frame rate should produce perfect A/V sync without dropouts if your harddisk can keep up on the average. MJPEGTOOLS ---------- I mainly use lavtrans for converting the avi/mjpeg file made with ffmpeg to quicktime format. This should be readable by most video editing software. I had some problems with sharing th avi/mjpeg files themselves. To convert the avi file to mov use: lavtrans -o clip.mov -f q clip.avi Mplayer/Mencoder ---------------- The MPlayer project uses libavcodec, and even distributes a copy with the MPlayer source. You'll need mencoder mainly if you want to use an encoder that's not in the ffmpeg package (lavcodec), or what to do some format conversion that's not supported by ffmpeg directly. Of course mplayer is handy for inspecting raw files. To play a raw video stream try: mplayer -rawvideo on:w=320:h=240:fps=25 video.i420 To encode video only using the ffmpeg (lavc) mjpeg codec (it is possible to use yv12 here, using the format=yv12 option) mencoder -rawvideo on:w=320:h=240:fps=25 video.i420 -ovc lavc \ -lavcopts vcodec=mjpeg -o clip.avi links ----- http://mjpeg.sourceforge.net/ http://ffmpeg.sourceforge.net/index.php http://libquicktime.sourceforge.net/ http://www.mplayerhq.hu http://libdv.sourceforge.net/ http://solarmuri.ssl.berkeley.edu/~fisher/public/manuscripts/scientific-movie-HOWTO.txt http://mpeg4ip.sourceforge.net/ http://heroinewarrior.com/cinelerra.php3 http://www.adamwilt.com/DV-tech.html pdp-0.14.1/doc/objects/000077500000000000000000000000001225432502200145535ustar00rootroot00000000000000pdp-0.14.1/doc/objects/README000066400000000000000000000003031225432502200154270ustar00rootroot00000000000000This directory contains help patches for the individual pdp modules and abstractions.

Date: Mon Nov 28 16:42:54 EST 2011 After I forked PF from PDP I've been working on many things that might deserve some re-integration into the PDP framework. I'm not too happy with the design of PDP. Every time I pick up PDP again I think the problems might be fixable, but then give up shortly after that, seeing that they are not.. A better approach might be to start a new system and make interfaces with Pd / PDP. List of problems: * Memory allocation / reference counting. This is fixed in PF but backporting would break PiDiP etc. * Interfaces. This includes Pd, PDP's packet interface, raw buffer processing, interfaces of ad-hoc modules (video i/o ...). * Composability on the instruction level, i.e. automate inlining and unrolling. Most algorithms are simple, but a lot of effort is spent in manually writing unrolled loops with simple formulas. Entry: Upgrading V4L Date: Tue Nov 29 13:19:49 EST 2011 According to IOhannes v4l1 is no longer supported in recent kernels (zoo: 2.6.33.7-rt29 still works). The preferred way is now to use libv4l. He had changed PDP accordingly. To install on Debian: apt-get install libv4l-dev In configure.ac I had to change "pkg-config libv4l" to "pkg-config libv4l2" to make it compile on debian.

Maybe it's best to go for SSE2 on the longer term, as it seems to have most of the saturated integer math that's necessary for PDP's feel. It would be nice to do some auto-vector code also.

What's going on here? 058f:b002 Alcor Micro Corp. Entry: zl_ Date: Wed Nov 7 21:32:28 EST 2012 Instead of mixing with libprim it seems best to just make a simple C library of utility objects. A basic reusable old-tech approach. librpim is too tied to the scripting idea, and is probably best tied to zl_ directly Oh, and zl_ stands for Zwizwa Library ;) I think I'm going to keep the language-foo out of PDP. PDP is good as it is: simple, straightforward. The only place I see for languages is at compile time, to generate code. Entry: Next Date: Thu Nov 8 21:45:59 EST 2012 - integrate xwindow.c object into PDP, replacing most of the pdp_xwindow stuff. maybe this needs a gl object first? - MMX resample: better fetch strategy Entry: Resampling Date: Fri Nov 9 11:05:50 EST 2012 I'm not sure any more if it is useful to do many pixels in parallel. It seems that at least some operations need to be done serially. -> What does need to happen is that 4 pixels are computed and stored together. So it makes sense to do part of the ops in parallel since result storage is in parallel. What about restructuring? What can be done in parallell is to compute the offsets of the 4 vectors to be fetched from memory, that would work out nice. The coordinates would still be stored in 2 vectors, but the 4 components are used to compute the 4 vector locations: (x,y), (x+1,y), (x,y+1), (x+1,y+1) The challenge in doing this is to encode that +1 somehow. Currently this can't be done exactly since the coordinates are in 0.32 image-relative coordinates to allow for easy wrap-around. I.e. need to guarantee that x * scale and (x+offset_1) * scale always point to neighboring pixel indices. is there any mathematical property that can guarantee this? It might really be simpler to just perform a compare + correction. I.e. a modulo that works only for a the vectors that are just outside the range. Do this in parallel: x_inc = x_inc > right_edge ? 0 : x_inc y_inc = y_inc > bottom_edge ? 0 : y_inc In MMX that is PCMPGTW followed by PAND _mm_cmpgt_pi16() _mm_and_si64() Entry: Pd as a dataflow compiler Date: Fri Nov 9 12:40:13 EST 2012 Time to make this work ey ;) New project: PDC : Pure Data Compiler. Arrange a network. The result is a DFG that can be given any kind of interpretation. Any time the DFG changes, it gets recompiled and re-loaded. Essentially, abstract evaluation. Entry: Resample Date: Sat Nov 10 15:17:55 EST 2012 I'm giving up for doing this in straight mmx: there doesn't seem to be a good way: most of the code is shuffling that can just as well be replaced by integer operations and possibly straight s16 memory accesses. I'm going to commit now and remove all the shuffling code. It was an interesting trip though :) Another thing: if all pixel increments are made such that they are always positive, and always smaller than the with/height of the image, a simple compare -> conditional subtract is actually enough to compute the integer/fractional addresses directly: no multiplication is necessary. However, it is nearly free. Entry: Bug Date: Sat Nov 10 20:37:49 EST 2012 So I thought I had a bug as my scanned synthetis patch was running so slow.

Entry: List parser Date: Sun Dec 9 11:57:09 EST 2012 Problem with interfacing OO C code with pd is just the control messages. What I want is some kind of straightforward way to map a pd list, i.e. |coef 123< to a function call x_coef(x, 123). This needs a dispatcher, or a "de-dynamicifier". The trouble here is type stuff: somehow the static C type need a run-time representation. Instead of parsing header files, it seems best to tackle this at the source, encoding the syntax in some CPP constructs that are easily evaluated to different parts (declaration, implementation, parser, ...) Using explicit markers: #define API \ FUN_BEGIN(float, set_coef1) ARG(float, c) FUN_END \ FUN_BEGIN(float, set_coef1) ARG(float, c) FUN_END \ Using macro varargs FUN(ID(float, set_amp, "Set amplitude"), ID(float, amp, "amplitude")) FUN(ID(float, set_coord, "Set 2D coordinates"), ID(float, x, "X coordinate"), ID(float, y, "Y coordinate")) Declaration is then: #define FUN(n, ...) n (__VA_LIST__); #define ID(t,n,doc) t n Let's try this out for the xv wrapper.

Entry: Prerelease Date: Tue May 14 14:32:13 EDT 2013 Hello, There's a PDP release in the pipeline: 0.14.0: Port ia32 MMX assembly code to GCC extensions (MMX support on amd64) Add V4L2 support to pdp_v4l (merge with pdp_v4l2) Distill zl (Zwizwa Lib) from PDP and libprim/PF code. This is quite a big change internally and is not 100% stable yet. It should be functionally equivalent with previous version. I'm going to put out what I have now for people that like to try it out. If you run into a bug, post here or send it to pdp@zwizwa.be http://zwizwa.be/pd/pdp/test/pdp-darcs-20130514_145023.tar.gz Some known issues are GLX crashes when texture size changes and V4L1 support being broken. ( See pdp_v4l_hack for a new camera-specific setup hack that was necessary to get high FPS on a Microsoft cam. It might be useful for other cams too. ) Cheers Tom Entry: Todo from pd-list Date: Wed May 15 20:19:40 EDT 2013 - find m_pd.h in different path WONTFIX? - fix default target DONE - weird images sizes sometimes crash (not in debug build?)

I.e. only do this in 3dp object? Entry: fixing scaf Date: Tue Oct 29 09:44:07 EDT 2013 Probably best to make a different architecture. It doesn't seem too hard to write this in pure C in an unrolled/tiled loop. Hmm... no. That's not a good tap point. It might be simplest to keep the code in 386 bit mode and do the ABI adaptation in the feeder routine. How to switch to 386 bit mode? Maybe only the OS can do that? Doesn't look like this will work. What is the code that goes into the assembler? In scafmacro.s the memory references are through %edi and %esi. Changing these to the 64 bit equivalents should be enough. Then fix the feeder to use a 64bit ABI. esi -> rsi edi -> rdi To make this work, make sure all .s files pass through the C preprocessor, then use: // 32bit #define SI %esi #define SI %esi // 64bit #define SI %rsi #define SI %rsi http://stackoverflow.com/questions/2500362/running-32-bit-assembly-code-on-a-64-bit-linux-64-bit-processor-explain-the Entry: Fix scaf Date: Sun Nov 3 12:52:07 EST 2013 - convert pdp_ca.c to fixed size ints from stdint.h - use minimal %esi / %edi fix for core routines - create inline asm feeder EDIT: Tried on Acer One 32bit, but pdp_opengl gives problems after recompile. Should do a fresh configure & compile and find out what's wrong.. No protocol specified pdp: x11: can't open display :0 It also happened a launching xterm, but now xterm works again. Not sure what the difference was. Let's restart X server. Yep, that fixed it. Guess is that there is another bug in the 3Dcontext -> Xlib calls that exposes a bug in the X server.

It is an implementation of the "Object Pool" pattern with lazy instantiation and lazy destruction. The pool is a growable array. It can only grow larger. Packets are represented by an integer, which is an index in this array. The standard "pure" packets (the ones which use a flat memory buffer) have recovery for resource depletion (main memory). If an out of memory condition is met on allocation of a new package, the garbage collector kicks in and frees unused packets until the out of memory condition is solved. Since an out of memory condition can be fatal for other parts of the program, pdp also supports a memory limit, to ensure some kind of safety margin. The "not so pure" packets should resolve resource conflicts in their own factory method, since the constructor is responsible for allocating external resources. The standard way to do this is to allocate a packet, free it's resources and allocate a new packet until the resource allocation succeeds. Especially for these kinds of packets, the pdp pool supports an explicit reuse method. This returns a valid packet if it can reuse one (based on the high level type description). Packets that don't have memory managing methods defined in the packet class (Standard packets) are treated as a header concatenated with a flat memory buffer, and can be copied and cloned without problems. So, if a packet contains pointers to other data or code, it can't be a pure packet. The interface to the packet manager contains the following managing methods: * pdp_packet_create: create a new packet * pdp_packet_mark_unused: release a packet * pdp_packet_copy_ro: register a packet for read only use * pdp_packet_copy_rw: register a packet for read/write use (this creates a copy if necessary) * pdp_packet_clone_rw: create a new packet using a template, but don't copy the data ( some types have shortcut methods pdp_packet_new_ which create/reuse a packet unless you are writing a factory method for a packet, you should NEVER call a _create method ) And two methods for raw data access * pdp_packet_header: retreive the header of the packet * pdp_packet_data: retreive the data buffer of the packet (only for static packets) All the methods declared in this header are supposed to be thread safe, so you can call them from the pd and pdp thread. */ #ifndef PDP_PACKET_H #define PDP_PACKET_H #include "pdp_symbol.h" #include "pdp_types.h" // this is legacy stuff: images are basic types #include "pdp_image.h" #include "pdp_bitmap.h" #define PDP_HEADER_SIZE 256 /* all symbols are C-style */ #ifdef __cplusplus extern "C" { #endif typedef int (*t_pdp_factory_method)(t_pdp_symbol *); //returns bool success /* packet class header */ typedef struct _pdp_class { /* packet manips: non-pure data packets (using external resources) must define these */ t_pdp_packet_method1 wakeup; /* called before returning a reused packet (rc:0->1) */ t_pdp_packet_method2 copy; /* copy data from source packet to destination packet */ t_pdp_packet_method1 cleanup; /* free packet's resources (destructor) */ t_pdp_packet_method1 sleep; /* mark_unused notify: called when refcount reaches zero */ t_pdp_symbol *type; /* type template for packet class */ t_pdp_factory_method create; /* the constructor: create a packet with uninitialized data */ }t_pdp_class; /* TODO: implement garbage collection for fobs.

See include/pdp.h and the sources in this directory for more info. There are 3 kinds of pdp messages: [pdp register_ro ] [pdp register_rw ] [pdp process] Together they form the pdp protocol. An object can receive a packet by catching the 3 kinds of messages: When a register_ro message is received, the object can call pdp_packet_copy_ro(packet) to reserve a read only copy for itself. The same goes for handling the register_rw message. You can reserve a read/write copy by using pdp_packet_copy_rw(packet) When a process message is received, the object is allowed to start processing the packet data end send the resulting packet(s) out. To send out a packet, use the pdp_packet_pass_if_valid(outlet, &packet) method. It passes a packet, and sets the reference to -1 (the undefined packet id). If you want to write pdp externs, consider using the pdp_base object to derive your object from. Have a look at pdp_add, pdp_gain, pdp_noise to see how to do this. pdp-0.14.1/modules/generic/000077500000000000000000000000001225432502200154415ustar00rootroot00000000000000pdp-0.14.1/modules/generic/Makefile000066400000000000000000000005141225432502200171010ustar00rootroot00000000000000current: all_modules include ../../Makefile.config PDP_MOD = pdp_reg.o pdp_del.o pdp_snap.o pdp_trigger.o \ pdp_route.o pdp_inspect.o pdp_loop.o pdp_description.o pdp_convert.o \ pdp_udp_send.o pdp_udp_receive.o pdp_rawin.o pdp_rawout.o pdp_metro.o # build generic modules all_modules: $(PDP_MOD) clean: rm -f *~ rm -f *.o pdp-0.14.1/modules/generic/README000066400000000000000000000001471225432502200163230ustar00rootroot00000000000000This directory contains generic packet processors (i.e. containers).

(3dp right now only supports window centric rendering itself, but adding pbuffer or pixmap rendering is easy enough, though it requires a rather new glx library) so, 3dp is an experimental gem clone with tight pdp integration. unless you like experiments, use gem, since it is better supported, has more features and runs on linux, windows and mac osx. requires glx (opengl on x window). building: edit Makefile.config to reflect your system and run make. the library is pdp_opengl.pd_linux some of the examples use the abstractions in opengl/abstractions. best to add this to your pd path. there are some fatal X bugs floating around, so be careful with resizing windows and closing patches. there are a lot of other, non-fatal bugs or badly implemented features. if you have remarks, just let me know. i'll move to autoconf once i no longer consider it experimental. TIPS & TRICKS * the 3dp_windowcontext creates a window to draw in. the window packet will be be output to the left outlet when a bang is received. control flow for context is right to left, this means if a 3dp object has 2 context outlets, the rightmost will be propagated before the leftmost. there is no fanout. all operations are accumulative, including the geometric transformations. if you need to branch use a 3dp_push object. * geometric transformations can be done using the 3dp_view object. the first argument is the kind of transformation: scale, scalex, scaley, scalez, rotx, roty, rotz, rota, transx, transy, transz, transxyz. repectively this scales the object, the x, y, z axis, rotates around the x, y, z axis, rotates around an arbitrary axis, translates in the x, y, z directions and translates along a vector. the initial parameters can be specified as creation arguments, i.e.: [3dp_view rota 1 1 1 90] rotates by 90 degrees around axis (1,1,1). * some simple objects can be drawn using the pdp_draw object. the first argument is the object: square, cube, sphere, torus, cone, teapot, dodeca, icosa, octa, tetra. prepending the names with a w draws the wireframe version. (i.e. wcube is a wireframe cube). the first inlet of the object is a texture inlet. not all objects support this, but cube, square and sphere do. other inlets set some parameters like size, nb of segments for sphere, etc.. they can be specified by creation arguments too. * saving a (matrix) state can be accomplished by the 3dp_push object. the default matrix is the modelview matrix. it works as follows: both the right and the left outlet propagate the same matrix state as the input. so in short you can use 3dp_push to split your rendering tree into parallel branches. the matrix types that can be pushed are: modelview, texture, color, projection. * setting a current matrix can be done using the 3dp_mode object. i.e. [3dp_mode texture] will map all geometric transforms to the texture matrix, for texture coordinate animation. the left outlet restores the current matrix back to the modelview matrix. * it is possible to send a render context trough a drawing/view transforming object multiple times. the easy way is to use 3dp_for, but other ways are legal too. this can be done to draw different versions of the same object. have a look at example01 how this can be done. it is also possible to send multiple render contexts trought the same rendering tree (i.e. multiple windows). if you use different viewing transformations on the top of the rendering chain, you can view a scene trough different angles. * light sources can be introduces using 3dp_light. they can be moved with oridinary 3dp_view objects. * 3dp_color changes the current color. right outlet is new color, left outlet is the previous color. * 3dp_toggle toggles a boolean opengl switch. enabled now are: depth_test, blend_add, blend_mix. more to come later. * couping 3dp and pdp can be done using 3dp_snap and pdp_convert. the correct way to do it is to put 3dp_snap in a rendering chain and give it arguments like this: [3dp_snap image/*/* 320 240] if you specify the subtype to be image/multi/*, the packet will not be colour space converted: it will stay rgb. if you want to make a snapshot to store as a high quality png image, snap to bitmap/rgb/* and store it in pdp_reg to save. to convert an image back to a texture, use [pdp_convert texture/*/*] if you snap to a texture (which is the default) the dimensions don't need to be specified. a texture will be allocated that can contain the entire screen. this is because texture coordinates are relative and data is always interpolated. snapping only works correctly when the window is not covered by other windows. * textures can have any dimensions, but only those which have dimensions that are integral powers of two will be tiled correctly. i.e. by using pdp_mode to change to texture mode and doing some coordinate transforms using pdp_view (see example06: this uses a tilable animated cellular automata texture) * multipass rendering is supported trough the objects 3dp_subcontext, "3dp_draw clear" and "3dp_view reset". the idea is as follows: before rendering the final scene, you use (a part of) the drawing buffer to render some things and store them in a texture to be used in your final drawing pass. have a look at examples 11, 12 and 13. in theory you could build a "texture processing" framework on top of 3dp, by using the window buffer as an accumulator and using textures as auxilary registers, and drawing your final texture result using i.e. 3dp_display_texture. while this can be much faster than ordinary pdp image processing, it also requires you to do more bookkeping yourself, since you can only use a "serial" approach because you can't modify textures directly, only trough the use of the render buffer. * 3dp has it's own thread, which is enabled by default. you can enable/disable this by sending a "3dthread 0/1" message to pdp_control. in most cases there's no reason to disable the thread processing, except when you are doing a lot of pdp<->3dp conversions. in that case the delay introduced by the thread processing might become problematic. (the same goes for pdp btw. feedback and threads don't mix too well). it's a tradeoff. thread processing gives priority to the audio, so you can obtain low latency, and you don't have to care about locking up pd by doing too much processing. (instead frames will be dropped). the drawback is of course that video timing becomes unpredictable because it is governed by the system scheduler. so sometimes it can be useful to disable threads and increase the audio latency, so you can have snappy audio and video at the same time. getting this to work well usually requires some experimenting. * if you have an nvidia card, you can set the environment variable __GL_SYNC_TO_VBLANK to 1 to prevent tearing, until 3dp has default support for it. i.e.: export __GL_SYNC_TO_VBLANK=1 enjoy, tom --- some political ranting: gem vs. pdp/3dp first a disclaimer. i'm not into dissing people. i respect and appreciate all the work that has gone into gem, but at the same time i'm not too happy with what gem has become. not so much the functionality, but the way it is built. the original design as a 3d processing extension is not flexible enough to incorporate what's in there now and what could be added in the future.. instead of complaining about it, i decided to be pragmatic and write something from scratch. i think, sometimes this has to be done. for me writing pdp/3dp has been an extremely interesting learning experience. i think i understand the trade-offs better now, and i know now it's not too easy to get it all to work. maybe these remarks can be useful... opengl is not a pure dataflow language. it operates on a global machine state next to the obvious drawing buffer that is passed around. representing opengl code with a graphic tree view has some advantages, though it has a different "feel" than normal pd patches. the fact that opengl transforms object coordinates to screen coordinates, and not vice versa, gives graphicly represented opengl code an "upside down" feel. one of the things i don't like about gem is that it has both the opengl "upside down drawing and coordinate transformation tree" and the pix "data flow image processing tree" in the same network, which i find counterintuitive. it is too monolytic to be truly flexible. in pdp/3dp i try to separate the two explicitly: dataflow where possible (image processing), and serial context based processing where needed (opengl). another disadvantage of gem is its window centric context. by building 3dp around explicit context passing, with explicit context creation objects, i try to avoid this. an advantage of this is the possibility to send multiple contexts trough a rendering tree, i.e. to have 2 different views of the same scene. pdp has implicit fanout for all packets. i think that is its great strength. it enables you to use any kind of media packet like you would use floats. it is very intuitive. however, 3d rendering does not fit this shoe. at least not when you just wrap opengl in the most straightforward way. 3dp is a test case for pdp's "accumulation packets", which is a formal abstraction of a context. pdp processors are nothing more than serial programs working on a context, so in fact it's nothing special. in fact, i'm still in doubt if it is useful besides being able to support opengl.. so, the idea was to improve upon gem a bit, from different angles. i did not succeed in my primary goal: making 3dp more intuitive than gem. it seems this is only possible if you limit some of the flexibility. just wrapping opengl keeps a lot of flexibility, but get's infected with the opengl paradigm. by separating pdp (image processing) and 3dp (drawing and geometry processing) as much as possible i think i've solved some intuition problems, but 3dp itself is still basicly gem, with imho a better overall design, but due to its more low level approach, maybe harder to understand. it seems to me that knowing how opengl works is rather necessary to use 3dp. the same is true for gem. one last philo remark: to me it seems the biggest drawback of gem's design is the processor centric aproach: the only objects are processors, the data is implicit and seemingly global. in pdp/3dp processors and objects are 2 separate entities. i tried to unify them in one object model, but to me it seems the two should really be treated as different complementary entities, to stay close to the dataflow paradigm which makes pd such an intuitive tool. pdp-0.14.1/opengl/TODO000066400000000000000000000112431225432502200143320ustar00rootroot00000000000000bugs: WARNING: there are still quite a few fatal bugs lurking around. * segfault when combining 3dp_windowcontext and pdp_xv. probably a mistake in the teture<->image conversion or window event handling. * 3dp is not robust against running out of video card resources. if you manage to crash it please consider sending a bug report. * 3dp_dlist triggered a segfault in pdp_mutex(un?)lock. can't reproduce. this also happens on some other occasions where a post() statement is involved: crash in pdp_mutex_lock, called by putc() -> happens in pdp too when calling post from thread (like in pdp_netsend/receive) * pd hangs on save?

DESIGN NOTES 3dp is basicly my idea of gem on top of pdp. it is a simple layer around opengl. 3dp_* render and transform objects accept a reference to a rendering context and pass this along. 3dp_* objects DO NOT SUPPORT FANOUT. they do support fanin. multiple contexts can be sent to an object, which will result in drawing in (or other manipulations of) the respective contexts. texture packets can be used to pass bitmap data around. 3dp_tdraw accepts a texture on its second inlet. 3dp_snap dumps the current state of the buffer into a texture packet. object classes: -drawing objects [3dp_draw cube] [3dp_draw sphere] .. -manipulation objects [3dp_view rot2d] -opengl stack objects [3dp_push color view texture] 3dp vs pdp design: a context packet is an accumulation packet, and the order of operations on it (serial) is important. it has elements from a readonly packet (only one instance is passed around) and from a rw packet (it is legal to change it's state and pass it on). opengl in dataflow formulation seems to be read bottom to top. i first thought this was a big drawback of gem, but now that i finally understand how opengl works i think it is ok. it suddenly dawned on me, usually the number of eyes is much smaller than the number of objects in a scene, so it is much more straghtforward to start at the eye instead of the objects. since a simple serial stack mechanism can be used. so opengl is really serial, while pd "looks" parallel, but is serial too. i still think this is a good thing, since it keeps things simple, but for some reason the "upside down & serial" thing about opengl in pd is rather strange.. once you get used to it, and think about rendering a set as a tree rooted at the "context source" like is done in gem,it seems to work out.. i think i'm going to stick to the depth first backtracking a tree serial rendering way of looking at it. since i don't see a way of making this more intuitive without complicating it too much. so no legal fanout of a context packet. ------------------ accumulation packets (buckets) & backtracking buckets add support for "context based" single threaded programs. it basicly allows you to construct data processors represented as a control flow tree. i.e. function calls can be represented by branches in a tree, with each branch rooted at an object's outlet, executed from right to left. a "context packet" (or accumulation packet or bucket) is passed along and acted upon. * fanout is illegal for bucket processors (at least, if they are non cummutative, as is usually the case). this is not explicitly prohibited, since it is hard to check in pd and it allows some hacks. the reason for this is obvious: if you do not know which branch of a tree is executed first, results are undefined. * a new communication protocol needs to be introduced, incompatible with the existing 3 phase protocol: (1) register_ro (2) register_rw (3) process the new dpd (bucket / accumulation packet) protocol is 2 phase: (1) inspect (2) accumulate (1) is only present to give priority to bucket inspectors over accumulators (processors) an accumulation packet will be owned by its creator all the time. accumulation processors do not increase the reference count. only ro inspectors will. note: it is legal for a packet to have a broken register_rw (missing copy constructor, i.e. if a copy is too expensive or impossible. this must be set in the pdp packet header flags by the packet constructor) pdp-0.14.1/opengl/abstractions/000077500000000000000000000000001225432502200163355ustar00rootroot00000000000000pdp-0.14.1/opengl/abstractions/3dp_basicscene.pd000066400000000000000000000013051225432502200215260ustar00rootroot00000000000000#N canvas 500 522 450 300 10;

Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR PDP.LICENSE, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

END OF TERMS AND CONDITIONS Appendix: How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.

The GNU Public Licence can be found in the file COPYING ------------------------------------------------------------------ This is a pdp extension lib that contains modules for cellular automata built on a (very) minimal forth-like virtual system (scaf - simple cellular automaton forth) to define update rules. a compiler is included to produce scafo object code that can be dynamically loaded into the pdp_ca module. so it is possible to add/change rules without restarting pd (note however you need to close all lib files before the dynamic loader reloads the lib). see scaf/README for details. pdp_ca2image and pdp_image2ca are included for conversion between CA packets and image packets. (pdp_ca2image produces greyscale images) Have a look at the patches in test/ for some crude docs. The file README.scaf contains some more info on the internals. Requirements: * pd * pdp * linux * perl for the forth compiler * an intel/amd processor that supports MMX Building: ./configure make make install If you don't have both libraries in the same dir and want to keep it that way, hardcode the paths in Makefile.config.in and run configure. You need to do "make install" to install the scaf compiler "scafc" and the default ruleset. This is to be able to load plain (text) rule files and have the default rules loaded when you create a pdp_ca object. Using: add "-lib /pdp_scaf" to the pd command line after the "-lib /pdp" part. launch pd with the options -lib $PDP_DIR/pdp -path $PDP_DIR/abstractions Directory structure: include/ header files pdp/ pdp external code compiler/ forth system code test/ some test patches (cryptic doc) rules/ ca rule libraries Please let me know if you discover a bug or think something doesn't work right. Code, documentation or example patches are more than welcome of course.

(%edi) = top row. lsb = left) scratch register: %mm1, %mm2 bitmask register: %mm3 = 0xffffffffffffffff 4 bit counter: %mm4-%mm7 the stack size / organization is not known to the stack machine. it can be thought of as operating on a 3x3 cell neightbourhood. the only purpose of the forth program is to determine the CA local update rule. the machine is supposed to be very minimal. no looping control. no adressing modes. no conditional code. so recursion is not allowed (no way to stop it) there are 9 words to load the cell neigbourhood on the stack. the rest is just logic and stack manips. the counter can be used for counting neighbourhood cells, like in the game of life. the zero test and sign bit can be used for comparisons. there are kernel words for loading constants into the counter register, and for communication between stack and register. the horizon is limited to 3x3, however it can be easily extended to 32x3. extending it further than that would require a redesign of the forth + feeder. HOW TO CREATE NEW CA RULES edit scaf/modules/carules.scaf or create your own source lib and add the name to the scaf/modules/Makefile. type make in scaf/modules to compile. if you get error messages from the assembler saying things like Error: no such instruction: `xxx' or Error: invalid character '_' in mnemonic this means there are undefined words in your source file. since not all characters are allowed in an asm file, the offending characters are converted to _SOMETHINGELSE_ if you are stuck somewhere, just look at the output of scaf.pl on your .scaf file to determine where the problem is. words that can be accessed from inside pdp_ca have to start with the prefix rule_ and have to leave a single item on the data stack (the return value) other rules can have all the stack effect you want, but for safety reasons they can't be accessed from within pdp_ca. FORTH SYSTEM CODE the forth system is made up of the following files: kernel.scaf: a collection of forth kernel words scafmacro.s: a set of asm macro definitions used in kernel.scaf optim.rules: some substitution rules to eliminate redundant stack manipulations scaf.pl: the compiler scaf.pl is run like this: scaf.pl -Isystemdir source.scaf if the -I switch is left out, the current directory is searched for the system files. the compiler produces an assembler source that includes scafmacro.s on standard output. the code it produces is relatively fast. it only uses and/or/xor and shift mmx instructions. it's not optimal use of silicon but it's pretty fast given what's possible. the feeder routine could be improved though. porting to another platform would require a rewrite of scafmacro.s the rest can be reused. if the target machine has 64 bit registers (or if you can emulate this one using more registers) porting is relatively easy. for larger registers a small change needs to be made to the feeder routine in pdp_ca.c pdp-0.14.1/scaf/TODO000066400000000000000000000002071225432502200137600ustar00rootroot00000000000000* add decimating to pdp_ca2image * clean up library * add translation option to pdp_ca (modify so horizontal shifts by 1 are possible) pdp-0.14.1/scaf/autom4te.cache/000077500000000000000000000000001225432502200160755ustar00rootroot00000000000000pdp-0.14.1/scaf/autom4te.cache/output.0000066400000000000000000004030021225432502200175150ustar00rootroot00000000000000@%:@! /bin/sh @%:@ Guess values for system-dependent variables and create Makefiles. @%:@ Generated by GNU Autoconf 2.69. @%:@ @%:@ @%:@ Copyright (C) 1992-1996, 1998-2012 Free Software Foundation, Inc. @%:@ @%:@ @%:@ This configure script is free software; the Free Software Foundation @%:@ gives unlimited permission to copy, distribute and modify it. ## -------------------- ## ## M4sh Initialization. ## ## -------------------- ## # Be more Bourne compatible DUALCASE=1; export DUALCASE # for MKS sh if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then : emulate sh NULLCMD=: # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which # is contrary to our usage.

PACK comes in two variants: signed and unsigned saturation. This is fairly straightforward. If you want to throw away lower bits, do a shift first. PACK does not interleave vectors. PUNPCK is the only one that interleaves vectors. It comes in two variants, taking data from the low or high words of the operand vectors. http://www.tommesani.com/MMXPrimer.html */ #include "pdp_imageproc.h" #ifdef DEBUG #define INLINE #else #define INLINE __attribute__((always_inline)) #endif /* pdp memory alloc/dealloc prototype */ void *pdp_alloc(int size); void pdp_dealloc(void *); /* This should be the native signed machine word, i.e. 64 bit on 64 bit arch, 32 bit on 32 bit arch. */ typedef int word_t; typedef union { __m64 v; s16 s[4]; // short u16 us[4]; // short word_t w; // only low 32 bits are used } v4_t; typedef union { __m64 v; u32 l[2]; // long } v2_t; #define CLAMP16(x) (((x) > 0x7fff) ? 0x7fff : (((x) < -0x7fff) ? -0x7fff : (x))) // utility stuff inline static s16 float2fixed(float f) { if (f > 1) f = 1; if (f < -1) f = -1; f *= 0x7fff; return (s16)f; } inline static void setvec(s16 *v, float f) { s16 a = float2fixed(f); v[0] = a; v[1] = a; v[2] = a; v[3] = a; } // GCC what? 4.7 ?? #define __builtin_assume_aligned(x,a) x // add two images void pdp_imageproc_add_process(void *x, u32 width, u32 height, s16 *image, s16 *image2) { __m64 *im = __builtin_assume_aligned((void*)image, 16); __m64 *im2 = __builtin_assume_aligned((void*)image2, 16); int a, b; unsigned int v, v_max = width * height / 4; for (v = 0; v < v_max; v++) { im[v] = _mm_adds_pi16(im[v], im2[v]); } _mm_empty(); } // mul two images void pdp_imageproc_mul_process(void *x, u32 width, u32 height, s16 *image, s16 *image2) { __m64 *im = (void*)image; __m64 *im2 = (void*)image2; int a, b; unsigned int v, v_max = width * height / 4; for (v = 0; v < v_max; v++) { im[v] = _mm_mulhi_pi16(im[v], im2[v]); } _mm_empty(); } // mix 2 images #define MIX_SIZE 8*sizeof(s16) void *pdp_imageproc_mix_new(void){return pdp_alloc(MIX_SIZE);} int pdp_imageproc_mix_nb_stackwords(void){return PDP_IMAGEPROC_NB_STACKWORDS(MIX_SIZE);} void pdp_imageproc_mix_delete(void *x) {pdp_dealloc (x);} void pdp_imageproc_mix_setleftgain(void *x, float gain){setvec((s16 *)x, gain);} void pdp_imageproc_mix_setrightgain(void *x, float gain){setvec((s16 *)x + 4, gain);} void pdp_imageproc_mix_process(void *x, u32 width, u32 height, s16 *image, s16 *image2) { __m64 *g = x; __m64 g_left = g[0]; __m64 g_right = g[1]; /* Do not multiply; copy image to allow for perfect feedback.

In order to use the 4 line parallel biquad routine on horizontal lines, we need to reorder (rotate or transpose) the matrix, since images are scanline encoded, and we want to work in parallell on 4 lines. Since the 4 lines are independent, it doesnt matter in which order the the vector elements are present. This allows to pick either rotation or transpose to go from horizontal->vertical. Rotations, transposes and flips are part of the 8-element non-abelean group of square isometries consisting of (I) identity (H) horizontal axis mirror (V) vertical axis mirror (T) transpose (diagonal axis mirror) (A) antitranspose (antidiagonal axis mirror) (R1) 90deg anticlockwize rotation (R2) 180deg rotation (R3) 90deg clockwize rotation We basicly have two options: (R1,R3) or (T,A) The choice seems arbitrary.. I opt for flips because they are self-inverting. Only one of T,A needs to be implemented with MMX unpack instructions. The other one can be derived by flips and both input and output.

It is a shared pool of objects used in pdp[1] and libprim[2]. Code is duplicated in those projects, and available as a stand-alone archive here[3]. License is defaulted to GPL, but drop me a line if you need something else. Note that some objects are stuck at GPL due to multiple contributors. Unmarked code is (c) 2003-2013 Tom Schouten Other authors are mentioned in the specific files. Some of these objects are from libprim and have stubbed-out code for the LEAF base object library.

See also the .h corrsponding to the .ap files for expansion into C prototypes. General idea The point of ZL objects is to be wrapped easily in different (dynamic) programming languages. It makes sense to make that process as easy as possible, avoiding a C parsing step by expressing object method descirptions in a more abstract format. The forms in the *.ap files can easily be manipulated using the C preprocessor to generate declarations and wrappers. The *.api files avoid C constructs such as "*" and "struct", and use only identifiers with alphanumeric characters and underscores "_". Note that this means object pointers need to be wrapped in typedefs, an approach which is often frowned upon. To avoid confusion with pointer/integral types, the _p suffix is used in Zl objects. Comma or not? The big decision is between these 2 forms: FUN(t, f, ARG(t1,a1), ARG(t2,a2)) FUN(t, f) ARG(t1,a1) ARG(t2,a2) END The former needs a macro with __VA_ARGS__, the latter has no separators between the arguments, and needs them built into the definition of ARG and FUN. A tale of C preprocessor hacking.. Comma-separated lists can only be mapped to comma-separated list with the same form. This allows 2 C constructs to be used: - Array / structure initializers - Function calls These 2 indirection mechanisms are fairly powerful, but they do are limited due to the presence of the comma, i.e. Note that there is a slight annoyance here: function declarations and calls to not take trailing commas. This means that ARG needs a leading comma, meaning that FUN needs to include the first argument. In practice this doesn't seem to be a problem, since all functions can be grouped by the type of their first operand (object pointer). Implicit object or not? To solve the trailing comma problem, it's probably best to also drop the object argument in the .api definition.

List representation ---------------------- There are essentially 2 kinds of list in C that are easy to use inside the language: - Static data initializers. This requires a union (optionally tagged) so has some syntactic overhead. Works for global and local variables. - Variable argument lists. This is a feature supported by the C standard and is very convenient to use as there is no notational overhead. Often converted data is short-lived, allowing data conversion to be implemented with nested C calls. Both are able to side-step malloc() when they are combined with some kind of callback mechanism. B.

    Pure Data Packet

    About

    PDP is an extension library for Pure Data, providing video and other media processing functionality. PDP's focus is on images and video, but there is support for matrix processing, 1D and 2D binary cellular automata and opengl rendering (like Gem). PDP runs on Linux and OSX. The OSX version depends on Fink.

    For more image processing objects, streaming objects and a collection of very useful additions to the bare bones PDP functionality, have a look at Yves Degoyon's PiDiP library.

    For documentation, have a look at the 'pdp' subdirectory in pd's 'Pure Documentation'. Most objects are documented with pd style help patches accessible by right clicking on an object. The place to send questions is the Pure Data mailing list.

    Download

    The latest stable PDP tarball release can be found in the PDP section of the Pure Data SourceForge project. The pd-pdp package is currently maintained by Paul Brossier. PDP is written by Tom Schouten and released under the GPL v2.
