CHAPTER 5 GEOMETRIC PRIMITIVES IN 2D
This chapter contains the definitions for various two-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 polygons, the object can be treated as a one-dimensional or a two-dimensional object. For example, the triangle as a one-dimensional object is just the closed polyline perimeter. As a two-dimensional object, the triangle refers to its polyline perimeter and the region that it bounds. Some objects ...
