      extended by visad.DelaunayFast
All Implemented Interfaces:
java.io.Serializable

public class DelaunayFast
extends Delaunay

DelaunayFast is a method of finding an imperfect triangulation or tetrahedralization of a set of samples of R^2 or R^3. It provides a substantial speed increase over the true Delaunay triangulation algorithms.
