Procedural Texture - Cellular Texturing

Cellular Texturing

Cellular texturing differs from the majority of other procedural texture generating techniques as it does not depend on noise functions as its basis, although it is often used to complement the technique. Cellular textures are based on feature points which are scattered over a three dimensional space. These points are then used to split up the space into small, randomly tiled regions called cells. These cells often look like “lizard scales,” “pebbles,” or “flagstones”. Even though these regions are discrete, the cellular basis function itself is continuous and can be evaluated anywhere in space.
