摘要
In this paper we investigate orthogonal polyhedra, i.e. polyhedra which are finite unions of full-dimensional hyper-rectangles, We define representation schemes for these polyhedra based on their vert ices, and show that these compact representation schemes are canonical for all (convez and non-convex) polyhedra in any dimension. We then develop efficient algorithms for membership, face-detection and Boolean operations for these representations.
