These are really cool examples, thanks for sending them. They all worked for me, except the fractal one was all black and there was a uniform float maxIterations; error
what was exactly the error?

Ooop please send any elementary examples of these things.
i post a few very diferents shader and the pd patch to use them here :

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)

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.

Thanks !!

GEM is a bit easier to deal with for shaders since there is no need
to do
any specific wrapper. Any ARB_ vertex or fragment shader and
any GLSL
shader you find on the web can work in GEM without modification.
In some
cases you might need to change something in the shader text to deal
with
rectangle vs 2D textures.
