Introduction

A coherent noise is a pseudo-random function. It can be used to create textures, or maps. The most well-known type of noise is probably Perlin noise. Noise functions, in general, can be the basic bricks for procedural generation of content.

Gamedev Framework (gf) provides several kind of 2D noise.
