[vtkusers] How to remove edges/faces not belonging to the konvex hull from Delaunay3D?

[lynx.abraxas at freenet.de]

Hello!


I  want  to get the convex hull of points lying on a sphere. I used Delaunay3D
for that. My problem now is the inner connection of points created during  the
Delaunay  triangulation (eg a line between opposite points of a octaedron). Is
there a way to remove the edges and faces that do not  belong  to  the  convex
hull?  I  found  vtkHull  but  that seems not to be the right filter for this,
since the Delaunay result contains the hull already,  it  would  just  need  a
clean up.

Thanks for any help or hints.
