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? By Loris from Italy
