[vtkusers] extracting delaunay triangulation from unstrucured grid

[Andrea Borsic]

Dear All,

I'm trying to use vtkDelaunay3D to triangulate a set of points in 3D and 
to subsequently save to file the tetrahydra obtained in such a way.

The funny thing is that the unstructured grid that is output by 
vtkDelaunay3D is composed by cell elements of type 3 (Lines). I was 
expecting it to be composed of cell elements of type 11 (Tetrahydra). 
This happens at least on the data set I'm using to test the small 
application.

Does anyone have a suggestion/explanantion, or had a similar problem ?

Thanks in advance for any help,

Regards,

Andrea.
