Calculating the Principal Views of a Polyhedron.

Abstract

This report examines the 'principal views' of polyhedra whose images are line drawings representing the images of edges. Several definitions for useful equivalence relations on the set of viewpoints are compared. An algorithm for enumerating the faces in each of the principal views of a convex polyhedron under perspective projection is given; this algorithm admits non-trihedral vertices. An implementation of the algorithm is described. Keywords: Object recognition, Polyhedral scene analysis.
