[PD] FW: GEM noobie: I don't understand this glsl thing... but I need it!

[Cyrille Henry]

the glsl exemples are in a specific folder in gem/exemple.
it's not very documented, but you'll have some basic shader.
it's a good place to start.

The idea for me is now to get a better understanding of the glsl chain, because it seems to be the place where all the magic happens. I thought I could find more examples of glsl objects implementations in pd, and some written code that I could try to hack... any help appreciated.
