[vtkusers] outline of a mesh

[Terry Hastings]

Thank u again Matthieu for your helfpful response
So do I really need vtkStripper tehn if the LODActor will automatically show 
the boundary of my unstructured grid if rendering time is too slow?
and so do you mean that vtkStripper should be able to extract all triangles 
in my unstructured mesh? or just teh boundary faces?  How do I specify for 
it to take the boundary faces only? so u're suggesting geometry filter is 
too slow?
okay thank u again!
Terry
