Introduction to Geometric Modeling COA 6764 Fall, 2007

The purpose of this course is to provide both the theoretical and practical background to develop working geometric modeling tools. The focus will be on planar polyhedra, however, the modeling tools developed are extensible to other types. The course will review the following topics: spatial transforms, including all those needed to develop a simple display pipeline; modeling solids as manifold polyhedra, with a focus on topology rather than geometry; the Euler operators for constructing shape topologies; shape and object operators, including: proximity testing, Boolean operations, shape shrinking and ballooning operations, slicing, and others. The focus will be the development of geometric rule checking, as found in various building design guides.
