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. c

Hi, and thank you for your answers, I know about extended view, I 've donwloaded it and used to build my design. 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.
