procedural texture - Computer Definition
An algorithmic way of describing a texture. Unlike a bitmapped texture, in which the texture is represented as a bitmap, a procedural texture describes the texture mathematically. Although not widely used, this method is resolution independent and can create more precise textures, especially if there is great and varying depth to the objects being textured. Procedural textures may be 2D or 3D. See texture mapping and volumetric texture.
