Class PerlinNoise

java.lang.Object
ActiverseUtils.PerlinNoise
public class PerlinNoise extends Object
PerlinNoise generates smooth gradient-based noise commonly used for procedural textures, terrain, and other effects. This implementation supports 1D, 2D, and 3D Perlin noise with support for fractal octave noise.

Based on Ken Perlin's original algorithm.
