Polytope and polyhedron
Web† Q2: When is a polyhedron a polytope? † A2: A polyhedron is almost always a polytope. We can give a counterexample to show why a polyhedron is not always but almost always a polytope: an unbounded polyhedra is not a polytope. Deflnition 4 A polyhedron P is bounded if 9M > 0, such that k x k• M for all x 2 P. What we can show is this ... WebPolytope. Given a convex polytope in three-dimensions of size O(n) along with an internal point which is the apex of the pyramids, there are only a polynomial ... Dobkin and Kirkpatrick [28, 29] present an beautiful static data structure for representing 3-dimensional convex polyhedra so as to answer tangent and intersection queries quickly.

WebFigure 4.1: (a) An H-polyhedron. (b) A V-polytope Obviously, polyhedra and polytopes are convex and closed (in E). Since the notions of H-polytope and V-polytope are equivalent … Webobjects (the coe cient cone and polytope) explicitly, but their parametriza-tions. In particular, one chooses a basis of kerAand coe cients from a certain polyhedron (ultimately, from a polytope) in order to generate the (positive part of the) coe cient cone, C > = kerA\Rm. Obviously, such a polyhedron (polytope) depends on the choice of a basis.
WebThis is appropriate, because, just as regular polyhedra are bounded by regular polyg ons, the regular polytope is bounded by regular polyhedra ("cells").
