[vtkusers] Delaunay3D Problem!

[Alex Jesus Cuadros Vargas]

I am using the 3D Delaunay triangulation to a set of points distributed
in two parallel planes. If the distance between the planes is small, the
resultant Delaunay triangulation shows problems, some tetrahedra are 
missing. I think this is a numerical problem. I am using VTK 2.3. 
Have you any suggestion? Do you know if the Delaunay triangulation in
VTK 3.1 is numerically more robust?

thanks
Alex
