Hello
I'm building the Voronoi diagram just for three sites (forming a triangle)
using the VoronoiDiagramBuilder. It works well. Printing the diagram looks good.
Then I get a QuadEdgeSubdivision of the VoronoiDiagramBuilder. I would assume
that the subdivision contains exactly one vertex inside my triangle
(representing the face) but it doesn't, even the Voronoi diagram includes such
a vertex. What's wrong?
Chris
Here is my code:
Geometry points = new WKTReader().read("MULTIPOINT ((0 0), (2 0), (1
2))");
// build Voronoi diagram
VoronoiDiagramBuilder voronoiBuilder = new VoronoiDiagramBuilder();
voronoiBuilder.setSites(points);
//System.out.println(voronoiBuilder.getDiagram(new
GeometryFactory()));
QuadEdgeSubdivision subdivision = voronoiBuilder.getSubdivision();
QuadEdge qe = subdivision.locate(new Coordinate(1, 1));
System.out.println("centroid of the triangle shouldn't be null: " +
qe.invRot().orig());
