[vtkusers] vtkPolyhedron

[Billy Araujo]

I am new to VTK.

I am using vtkPolyhedron but I find it strange that it doesn't have a
built in method for volume calculation like vtkTetra::ComputeVolume.
Also why do I need to create vtkUnstructuredGrid to Clip a single
polyhedron and pass so many parameters? Doesn't the vtkPolyhedron
have:
vtkPointData * 	inPd, vtkCellData * 	inCd information? If so, why is
it passed as parameter?
