[GEM-dev] glsl sample3d textures

[Dave Griffiths]

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.
