CHAPTER 9 GEOMETRIC PRIMITIVES IN 3D

This chapter contains the definitions for various three-dimensional geometric primitives that are commonly used in applications. Some of the primitives have multiple representations. A geometric query involving an object might be more effectively formulated with one representation than another. The discussion about a query will indicate which representation is more appropriate.

In geometric queries with objects such as polyhedra, the object can be treated as a two-dimensional or a three-dimensional object. For example, the tetrahedron as a two-dimensional object is just the collection of four triangle faces. As a three-dimensional object, the tetrahedron refers to its faces and the region that it bounds. ...
