Title :
Calculating the principal views of a polyhedron
Author_Institution :
Dept. of Comput. Sci., Rochester Univ., NY, USA
Abstract :
The principal views of polyhedra whose images are line drawings representing images of edges are examined. Several definitions of 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 nontrihedral vertices. An implementation of the algorithm is described
