[vtkusers] Planes intersection

[James C. Moore]

Hi,

You can use the planes to clip each other if you can  decide which side of
each plane is the one you want to clip.  The points for each plane could be
used to define both polygonal planes and clipping planes.   Use the clipping
planes to clip the polygonal ones.
