Hi,
I need some help...I'm trying to compute a bounded voronoi diagram in
MATHEMATICA 5. The code is:
gxy = {{4.4, 14}, {6.7, 15.25}, {2.1, 11.1}} $generators of Voronoi diagram
b = {{0, 1}, {14, 1}, {14, 16}, {0, 16}}; $boundaries
{vxy, gface} = BoundedDiagram [ b, gxy, delval, convexhull];
DiagramPlot[data2D, vxy, gface,Axes->True, AspectRatio->1,
AxesOrigin->{0,0}]
and so on and so forth following the instruction explained in the
MATHEMATICA BOOK.
But it doesn't work, that is, after the command {vxy, gface} =
BoundedDiagram [ b, gxy, delval, convexhull ];, if one tries to applay this
command to less than eleven points the output is:
"BoundedDiagram::notuniq: BoundedDiagram requires that boundary vertices lie
in unique Voronoi polygons. BoundedDiagram::nobd: Bounded diagram failed."
Whereas with more then 10 points all it's ok....
Why? Can anybody help me?
