[vtkusers] Extract polylines from the surface

[Cory Quammen]

David,

It would help if your questions were more specific. For instance,
which polylines do you want to extract from your surface?

Do you want all the edges between polygons? See
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/ExtractEdges

If you want to extract edges that have only one polygon on a side for
instance (to give one definition of the bounds of the surface), see
http://www.vtk.org/Wiki/VTK/Examples/Cxx/Meshes/BoundaryEdges

Thanks,
Cory
