i post a few very diferents shader and the pd patch to use them

"examples" section of Pd-extended.well, i think i should clean up some code and check licence for the
shader i did not write. where should i put them in order to include them in pd-extended?
Ok, no rush on getting them into CVS. I was thinking even that it
might make sense to make abstractions that wrap the Gem glsl shader
loading stuff so people could just use them as Pd objects without
knowing the details.
I think this would work well in the "externals" section, maybe as
it's own lib, with the abstractions and the shaders. And yes,
licenses are important.
Also, look for some serious shader action from vade, who's mostly
using Jitter these days. Thanks to your examples, I think he'll
start testing the shaders that he's writing with Gem in addition to
Jitter (maybe he'll chime in here on this thread).

I got confused by the Gem docs (they don't explain OpenGL as
thoroughly as the vanilla Pd-docs explain DSP).Gem doc aim is to explain gem specific stuf. but in order to use
Gem, you also need a good openGL book. (you can find lot's of them)cyrille

Hi all ! The Toon.vert and Toon.frag shaders don't seem to work quite well here. I only get some kind of darker or lighter grey depending
on the value of the "Phong" variable I set it to have. I am using Pd- extended 0.39-2 test 5 on Ubuntu Linux Intel. Gem is 0.91-cvs compiled
on Mar 16 2007. Should I generate something any better ?this is exactly what the toon shader is aiming to do. look at it's code to undersant why.
Anyone has an other GLSL shader to suggest to try it with ?
yes, google has a lot.
i have a few other exemple on my computer, tell me if you're
looking for some specific stuf.cyrille
Thanks !!
