so this project is basically nothing more than a python to GLSL translator.
https://github.com/ncbray/pystream
you have to follow the GLSL rules with the python code, so usage isn't exactly free.
the problem though is Nick Bray only documented a little about how to code the shaders, and gives no examples of calling the shaders in your GL app.
as far as it looks, there seems to only be 1 function to call which translates a python file to a GLSL shader
(not sure about the filetype used).
I'm not sure if it initializes GLSL and auto-uploads the GLSL code to the GPU or what...
I'd actually like to improve this so you can in-line python shader code within your actual code,
but the code uses python implementations I havn't yet figured out (such as the with statement).
