Have you tried the noise command? It's in the spec, but I think it's hit and miss how much vendors support it.
It's better to generate these procedurally to avoid the memory requirements, I'm sure there is some perlin glsl source around if your driver doesn't support it.
hmm, did not think about that, how are 3d perlin noise textures rendered then? are they rendered in realtime? only one frame? marius.

There really isn't 3d texture support in GEM. Now that GPUs have a fair amount of RAM it might be a good feature to add (512x512x512xRGBA is a lot of memory).

hi again, how can I create and/or load 3d textures (like 3d perlin noise) to a glsl program, so that I can use them for sampler3d textures? marius.
