[vtkusers] Clipping a volume

[Leila Baghdadi]

Hi Chunyan

When you create a plane using (vtkPlane), Set the origin of the plane to 
the origin of the data set (make sure you specify z around where you want 
to be) also set normals to (0,0,1) or (0,0,-1), 
depending on the direction of the normals and where you have set the 
origin of the plane part of the data will be gone (in z direction).


Hope this helps
