Package com.jme3.terrain.noise.fractal

Class FractalSum

java.lang.Object

com.jme3.terrain.noise.basis.Noise

com.jme3.terrain.noise.fractal.FractalSum

All Implemented Interfaces:

Basis, Fractal

public class FractalSum
extends Noise
implements Fractal

FractalSum is the simplest form of fractal functions summing up a few octaves of the noise value with an ever decreasing roughness (0 to 1) amplitude lacunarity = 2.0f is the classical octave distance Note: though noise basis functions are generally designed to return value between -1..1, there sum can easily be made to extend out of this range. To handle this is up to the user.
