org.xith3d.terrain.legacy.heightmap
Class Faulting

java.lang.Object
  org.xith3d.terrain.legacy.heightmap.HeightMap
      org.xith3d.terrain.legacy.heightmap.Faulting

All Implemented Interfaces:

java.io.Serializable, Terrain

public class Faulting
extends HeightMap
implements Terrain

Generates a heightmap using fractal faulting. The Algorithm was adapted from Aurel Balmosan's 'faultmap' program posted to Usenet by Carl Burke. Carl has an example and explanation here: http://www.geocities.com/Area51/6902/t_fl_app.html. Converson to the HeightMap class by William Denniss.
