Error in identifying boundary edges using vtkFeatureEdges
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Please find the attached sample program and input file. When I rub vtkFeatureEdge filter with BoundaryEdgesOn(), ideally I would expect the filter to return two boundary edges. But, one of the edge is highly discontinuous and return 12 edges in place of one. I tried cleaning the polydata but without success. When I tried edge identification for the same input in SolidView(ref: www.solidview.com), it gives me a correct output (it fails even in paraview). The following are the steps I followed to produce the error in Paraview.
1.Input(the given input file "sample.vtk") 2.FeatureEdge filter 3.Tube Filter(for better visualization) 4.Connectivity Filter (actually there should be only two unconnected edges, but here I get 13 edges)
