If you use a vtkIdFilter before the FeatureEdges filter (a demo here:
http://www.vtk.org/Wiki/VTK/Examples/Cxx/PolyData/PointCellIds) - there
will be an 'ids' array in the output that you can use to get the ids of the
boundary vertices. Write out the FeatureEdges output to a vtp and read it
with Paraview to see the contents of this array easily.
