Class TriangulationVertex

java.lang.Object
  net.nexttext.renderer.util.PlanarVertex
      net.nexttext.renderer.util.TriangulationVertex

public class TriangulationVertex
extends PlanarVertex

Used to do a triangulation of a complex polygon. Please note that you should make sure all of these vertices are two-manifold, if they are not the triangulation will fail with nullpointers.
