[vtkusers] vtkDelaunay3D

[Alessandro Artusi]

Jerom,

sorry, I was suppose to send it also to vtkuser mailing list, something went
wrong.

By the way this is teh email that i sent to you previuosly:

Dear Pam and Jerome,
thanks a lot, your emails have clarified to me many aspects.
I have tried what you have suggested Pam, but I get this error:
Generic Warning: In /build/buildd/vtk-5.0.4/Common/vtkMath.cxx, line 394
Unable to factor linear system
Delaunay return me this warning.
Any suggestion?
Thanks a lot again,
Alessandro.

Concerning your question if I get the result that i expect is not, I do not
get anything out of it.

Thanks,
Alessandro.
