[vtkusers] Clipping/ Cutting

[João Paulo Simonaio Pompei]

Hi,

I have non-structured grid images, slices of a volume(slices of a magnetic resonance). I have to cut one of this slices(think in a Doctor cutting a x-ray of
a patient), but only for visualization. What class can I use for do it? I looked vtkCutter, but this class takes a PolyData. If i'm wrong and vtkCutter is
the right class to use or you know the class i want, please help-me.

Thanks for any help,
Joao Paulo S. P.
