I think that the fractal patch has some initialization settings, and that I'm just putting in the wrong numbers, or there is a texture map that I don't have? By the way what is the difference between the ~ and no ~ frag & vert?
This is my graphics card:
NVIDIA GeForce 6600:

this is normal (it does the same on my computer).
so, i don't understand why it does not work on your computer. do you have an old graphic card (or old driver)? maybe the loop instruction are not implemented in older hardware.

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)
