java.lang.Object
  org.newdawn.slick.geom.OverTriangulator

All Implemented Interfaces:

java.io.Serializable, Triangulator

public class OverTriangulator
extends java.lang.Object
implements Triangulator

A triangulator implementation that splits the triangules of another, subdividing to give a higher tesselation - and hence smoother transitions.
