[vtkusers] Probing point values

[Darshan Pai]

I have a polyData . This polydata was generated by the vtkContourfilter
operation on a volume. The polydata has a closed topology
Now I want to texture the polydata.

What I need done is that for each point on the polydata I move the point a
set distance along the normal in the opposite direction and then probe the
value at that point location within the volume. Is there any way to get an
updated list of points which are all added by the inverse normal ?

I hope I am clear
