Gradient noise

From Wikipedia, the free encyclopedia

Gradient noise is a type of noise commonly used as a procedural texture primitive in computer graphics. It is conceptually different, and often confused with value noise. This method consists of a creation of a lattice of random gradients, which are then interpolated to obtain values in between the lattices. An artifact of some implementations of this noise is that the returned value at the lattice points is 0. Unlike the value noise, gradient noise has more energy in the high frequencies.

The first implementation of a gradient noise function was Perlin noise, credited to Ken Perlin, who published the description of it in 1985. [1]
