<p>Geometric algebra is a consistent computational framework in which to define geometric primitives and their relationships. This algebraic approach contains all geometric operators and permits specification of constructions in a coordinate-free manner. Thus, the ideas of geometric algebra are important for developers of CAD systems. This article gives an introduction to the elements of geometric algebra, which contains primitives of any dimensionality (rather than just vectors) and an introduction to three of the products of geometric algebra-the geometric product, the inner product, and the outer product. These products are illustrated by using them to solve simple geometric problems.</p>
