Envelopes of Surfaces in 3D
Reference Manual

Dan Halperin, Michal Meyerovitch, Ron Wein and Baruch Zukerman

Introduction

This package consists of functions that compute the lower (or upper) envelope of a set of arbitrary surfaces in 3D. The output is represented as an 2D envelope diagram - a planar subdivision such that the identity of the surfaces that induce the envelope over each diagram cell is unique.
