Perlin noise for image generation


Perlin noise is ubiquitous in modern CGI. Used for procedural texturing, animation, and enhancing realism, Perlin noise has been called the "salt" of procedural content. Perlin noise is a type of gradient noise, smoothly interpolating across a pseudo-random matrix of values.

The noise library includes native-code implementations of Perlin "improved" noise and Perlin simplex noise. It also includes a fast implementation of Perlin noise in GLSL, for use in OpenGL shaders. The shader code and many of the included examples require Pyglet (, the native-code noise functions themselves do not, however.
