TitleEfficient and Accurate B-rep Generation of Low Degree Sculptured Solids Using Exact Arithmetic
Author(s) John Keyser, Shankar Krishnan, Dinesh Manocha
TypeArticle in Conference Proceedings
AbstractWe present efficient representations and algorithms for exact
boundary computation on low degree sculptured CSG solids using exact arithmetic. Most of the previous work using exact arithmetic has been restricted to polyhedral models. In this paper, we generalize it to higher order objects, whose boundaries are composed of rational parametric surfaces. We present the underlying representations
necessary in our approach, and provide an overview of the boundary computation algorithm, which is described in more detail in a followup paper.
