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

[David Schaffer]

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.
 
David
