Collision Detection for Moving Polyhedra
(1984-10-01)We consider the problem of moving a three dimensional solid object among polyhedral obstacles. The traditional formulation of configuration space for this problem uses three translational parameters and three angles ...

Prism Trees: An Efficient Representation for Manipulating and Displaying Polyhedra with Many Faces
(1985-04-01)Computing surface and/or object intersections is a cornerstone of many algorithms in Geometric Modeling and Computer Graphics, for example Set Operations between solids, or surface Ray Casting display. We present an ...
