[vtkusers] How to get the cutting cells?

Hello,

I've got a vtkPolyData and a vtkImplicitFunction to cut through it, e.g. 
by using a vtkClipPolyData or vtkCutter. How can I retrieve the cutting 
cellId's?

I have tried it with a vtkThreshold and the scalar data, but I don't 
know further. Extracting polydata is not the right way, since I've to 
change my existing polydata dynamically and this is only possible if I 
know the respective cells.

Thanks for any suggestions.

Cheers,
Philipp
