[vtkusers] outline of a mesh

[Terry Hastings]

hi mathieu thank u for your response
so i should use a geometry filter on my original mesh to get the outline?
won't this not help with my speed problem because the pipeline is processing 
many more nodes/elements and then again going through this extra 
GeometryFilter..?
i thought unstructured grid could represent any type of combo of cells 
types..?
but i guess this  type of outline is not possible then?
