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. + + + +
