Ignore my last email, it will probably be much easier to use the
vtkFrustumSource.  It doesn't do exactly what you want (it needs the
frustum as a vtkPlanes object, not as eight points) but it's still
much better than having to build the polydata from scratch.  You just
have to create a vtkPlanes object from your eight points.
