WebIf we've already proven the above theorem, then your question is rephrased as "Is the intersection of two polytopes itself a polytope?" The answer to this is obviously "yes," as the intersection of two bounded sets is bounded and intersecting an intersection of finitely many closed [affine] half-spaces with another intersection of finitely many closed [affine] half …

A number of algorithms are known for the three-dimensional case, as well as for arbitrary dimensions. Chan's algorithm is used for dimensions 2 and 3, and Quickhull is used for computation of the convex hull in higher dimensions. For a finite set of points, the convex hull is a convex polyhedron in three dimensions, or in general a convex polytope for any number of dimensions, whose vertices are some of the points in the inp…
