Class WaveNoise

java.lang.Object

squidpony.squidmath.WaveNoise

All Implemented Interfaces:

Noise.Noise2D, Noise.Noise3D, Noise.Noise4D, Noise.Noise5D, Noise.Noise6D

@Beta
public class WaveNoise
extends java.lang.Object
implements Noise.Noise2D, Noise.Noise3D, Noise.Noise4D, Noise.Noise5D, Noise.Noise6D

A variant on gradient or Perlin noise, explored by Inigo Quilez here and initially discovered by "robobo1221". It is similar to ClassicNoise but produces more of its output in the extreme range (close to -1.0 or 1.0) than Perlin ever does.
This is still a work in progress.

Method Detail

zigzagTight

protected static double zigzagTight(double value)

Just in case we need a version of NumberTools.zigzag(double) that outputs 0.0 to 1.0.

Parameters:

value - any double (except NaN)

Returns:

a number between 0 and 1, linearly interpolating between the two at each integer peak or valley
