Computing Visibility Subsets in an Orthogonal Polyhedron

Authors: Jefri Marzal, Hong Xie, Chun Che Fung


Visibility problems are central to many computational geometry applications. One of the typical visibility problems is computing the view from a given point. In this paper, a linear time procedure is proposed to compute the visibility subsets from a corner of a rectangular prism in an orthogonal polyhedron. The proposed algorithm could be useful to solve classic 3D problems.

Keywords: visibility, rectangular prism, orthogonal polyhedron
