[vtkusers] collision detection with vtk?

[-Daniel-]

I tried your hint with vtkIntersectionPolyDataFilter.
My using this filter:
..
intersectionPolyDataFilter.SetInputData( 0, constantPolydata);
intersectionPolyDataFilter.SetInputData( 1, movedPolydata);
intersectionPolyDataFilter.Update();

If I move the movedPolydata I must set the second InputData again.
Therefor get the movedPolydata with this new position.
..
intersectionPolyDataFilter.SetInputData( 1, movedPolydata);
intersectionPolyDataFilter.Update();

This is terrible slowly.

How I get faster than before of the updated datas? Any ideas?
