Class Noise

java.lang.Object
  |
  +--render.Noise

public final class Noise

extends java.lang.Object

Computes Perlin Noise for one, two, and three dimensions.

The result is a continuous function that interpolates a smooth path along a series random points. The function is consitent, so given the same parameters, it will always return the same value.
