Class DelaunayFast

java.lang.Object
  visad.Delaunay
      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.
