[vtkusers] Extracting surface triangles (eliminating inner triangles)

[bailleul jonathan]

Dear All,

I know the topic is quite covered already, but I didn't manage to find 
my solution in the list so far...

I have a closed surface obtained from 3D delaunay (tetgen). It is 
already a polydata made of triangles, but since it is infered from 
tetrahedrons, there are many many inner triangles 'inside'.

I would simply like to get rid of them, and only keep the 
"boundary"/outer triangles.

Please note that I neither don't want to add any vertices nor move the 
existing "outer" vertices.


With my best regards,
