[John Platt]

Have you looked at vtkExtractEdges or vtkFeatureEdges?

Subject: [vtkusers] Extracting edge regions of a surface

 

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
