[vtkusers] vtkPolyDataContourLineInterpolator

[Karthik Krishnan]

Yes. I wrote this class to interpolate points on the mesh. You may want to
take a look at its concrete subclasses
(vtkPolygonalSurfaceContourLineInterpolator) and at the test :

Widgets/Testing/Cxx/TestDijkstraGraphGeodesicPath.cxx to trace contours on
a surface mesh. It is meant to be used in conjunction with a
vtkContourWidget and is capable of giving you the new polydata (see
vtkContourRepresentation::GetContourRepresentationAsPolyData()).

You may also get the contour pointIds itself as point ids on the original
mesh on which the contour was traced.  See
vtkPolygonalSurfaceContourLineInterpolator::GetContourPointIds(
vtkContourRepresentation *rep, vtkIdList *idList );
