FW: [vtkusers] Extracting edge regions of a surface

[Gil]

Yes, but those filters give me ALL the edges in one group..
I am looking for a way to separate them to say, 4 edges, in the quad case.

  Have you looked at vtkExtractEdges or vtkFeatureEdges?

  Hi,

  To extract faces of a volume I do the following:

  vtkDataSetSurfaceFilter -> vtkPolyDataNormals -> vtkConnectivityFilter(for
each region).



  Is there a way to do it for surfaces - extract each edges as a region?
(i.e. for a quad - extract 4 different edges).



  Thanks,

  Gil
