A blog post from kevin goldsmith http://blogs.adobe.com/kevin.goldsmith/2008/09/spilling_the_be.html says that adobe is soon going to release a command line compiler for pixel bender. has there been any progress on this as i'd really like to get my hands onto it.
is the compiler going to be open source, so we can have a look at the opcodes or atleast the EBNF grammar. if not open source is adobe going to release any technical specification as they have done for swf file format specification.
The command-line compiler was part of "pre-release 5" that was released several months ago. You can download it as part of the latest release of the Pixel Bender Toolkit on Labs. (see: http://labs.adobe.com/technologies/pixelbender/releasenotes.html)
We are discussing several options around opening up aspects of the Pixel Bender to Pixel Bender Bytecode compiler. Watch my blog (http://blogs.adobe.com/kevin.goldsmith) for more info.
could you guide me to the ebnf/bnf grammar of pixel bender? just want to write a small parser that tries to converty pixel bender source code to a shader class, and automatically fills in the setter and getter functions.
also want to do some sort of automatical filling of static for loops for flash player (loads of copy pastes), and some other handy utility functions.
with the bnf grammar i could fit it in with a parser, get the AST out, mess with it, print it back, and send to pixel bender compiler, and get the shader code.
