Curtis, In my previous email I meant ... your rule of "voronoi polygons vertex = centroid of triangles" ... rather than ... your rule of "voronoi polygons edges = centroid of triangles" ... I hope this doesn't cause confusions. Ricardo Curtis Rueden wrote:
Hi Ricardo, VisAD does not contain any code to construct Voronoi polygons, but the Delaunay logic includes everything you need to easily create them yourself. Each Voronoi polygon is computed by finding the center point of each triangle/tetrahedron (average of Tri vertex samples), and connecting those center points across the triangle edges/faces (using the Walk array). Alternately, you could feed the results of a triangulation in VisAD to some external software capable of computing Voronoi diagrams from an input triangulation. -Curtis On 1/31/07, Ricardo Mantilla <ricardo@xxxxxxxxxxxxxxxxxx> wrote:Hi, Has anyone developed methods to obtain the Voronoi polygons from a Delaunay triangulation? I think this question was asked some time ago and at the time there was no such class implemented.
