[vtkusers] delaunay 3D with very close points

[pam]

hi all, I was trying Delaunay3D with some points and I found that it
has problem when are very close in Z in my case.
This is my groups of points and in Z the points are so near that I
think the algorithm are taken this in the same plane because I can´t
see anything
with Delaunay3D but I can see something in delaunay2D. I was playing
with setAlpha and setTolerance but I couldn't make it work. There is
any solution? Maybe could I change the referential in Z?

pts->InsertPoint(0,25783.132,11566.265,1204.81926);
pts->InsertPoint(1,22435.896,14102.563,1282.0512);
pts->InsertPoint(2,24875,13875,1250);
pts->InsertPoint(3,26097.56,12804.878,1219.5122);
pts->InsertPoint(4,27926.829,13780.487,1219.5122);
pts->InsertPoint(5,31923.076,14743.589,1282.0512);
pts->InsertPoint(6,24000,17625,1250);

Thanks in advance.
