I have a 3D Nef polyhedron.  I want a 2D polygon representing the silhouette
of that polyhedron (bird's eye view).  I've been looking at Envelopes but am
unsure if that is the way to proceed.  Wouldn't it be easier just to glide
it through the xy plane, intersect it there and then use that intersection
to build my polygon?

If envelopes are the correct way to do this, I find the three examples are a
little too different to what I need to be of any real use.  Does anyone have
a better example lying around the place?
