- Well, PROF Rogers, that may be the Navy way, but it's not the right way.
- It's not even the *wrong* way.
-
- Is it possible that someone on comp.graphics has finally posed a
- question which cannot be answered by citing an ISBN number?
-
- Here's a nice simple question to keep everyone occupied (sit down Joe -
- this one's not for you).
-
- GIVEN an arbitrary, simple polyhedron, P.
-
- FIND the largest (greatest volume) convex polyhedron completely
- contained in P.
