   what are homogeneous non-periodic textures?
  Anyone knows about some articles/tutorials discussing these terms/techniques?

If you want something more specific you'll need to give some context (I've certainly never heard of the term before).   ;  wow! a texure that has a uniform appeareance yet doesn't have periodic(tiling) issues?That sounds really useful for texturing my terrainI wonder how you make one.....   ;Quote:Original post by haphazardlynamedwow! a texure that has a uniform appeareance yet doesn't have periodic(tiling) issues?That sounds really useful for texturing my terrainI wonder how you make one.....see this doc;  Procedural texturing often has these qualities. For example if you have a system that uses a Perlin noise function to get a color based on x,y,z coordinates of the pixel/texel, it's essentially an infinitely large 3d texture that doesn't repeat yet it'll have a homogenous appearance over a large area. This type of texturing is traditionally used in ray-tracing but it's possible to do it in real time with shaders on modern GPU's... I've seen clouds done this way (although I think it used a tiled "noise texture" to make the Perlin-like noise so it'd probably have some tiling).
