I don't think any filters will really change the values.  You can use this:

http://www.vtk.org/Wiki/VTK/Examples/PolyData/ThresholdingPoints

<http://www.vtk.org/Wiki/VTK/Examples/PolyData/ThresholdingPoints>to get the
IDs of the points that pass your threshold test and then set to the specific
value yourself.

Maybe someone has a better answer?

Thanks,

David
