[vtkusers] Probing point values

[Bill Lorensen]

WarpVector will move polydata points along a vector. You can control the
amount of displacement with a ScaleFactor.

Here is an example: http://vtk.org/Wiki/VTK/Examples/Cxx/PolyData/WarpVector

Once you have the displaced points, you can use vtkProbeFilter to sample
the volume.
