  +--render.ImprovedNoise

public final class ImprovedNoise

extends java.lang.Object

Improved version of Noise.

Algorithm:
Find unit cube that contains point (x, y, z).
Find the relative x,y,z of the point in the cube.
Compute the fade curves for each of x,y,z.
Hash coordinates of the eight cube corners and add blended results from the eight corners of the cube.
Return the sum.
