noise 1.0b3

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 (http://www.pyglet.org), the native-code noise functions themselves do not, however.

The Perlin improved noise functions can also generate fBm (fractal Brownian motion) noise by combining multiple octaves of Perlin noise. Functions for convenient generation of turbulent noise are also included.

Version 1.0b3 fixed problems compiling with Visual C++ on Windows. Thanks to Stas Kounitski for fixing this issue!
