Class IncrementalTinDual

java.lang.Object

micycle.pgs.commons.IncrementalTinDual

public class IncrementalTinDual
extends Object

Produces a (barycentric) dual graph from a TinFour Delaunay Triangulation. Triangle centroids form the vertices of the dual graph, and each triangulation vertex corresponds to a face in the dual graph; the dual graph has similarity to the voronoi diagram, but it isn't the same.

The dual of (fairly) regular triangulation is a regular polygonal (hex/oct) mesh.
