Abstract
A method for rendering a polytope in a volumetric display includes partitioning the polytope into a plurality of polytope sections, each of the polytope sections being disposed in an active slice defined by an entry plane and an exit plane. The presence of an imaging screen within the active slice is then detected. While the imaging screen is within the active slice, a connecting polygon is defined on the basis of a projection of the polytope section on the entry plane. This connecting polygon is then rendered on the imaging screen.
