Computer Graphics introduces the basic concepts and techniques of modern interactive computer graphics, assisting readers in writing practical application programs. Designed for a one- or two-semester course, this new text begins by presenting simple routines that produce pictures. It then proceeds, in a step-by-step fashion, to develop the methods for creating more complex drawings. In addition, this book incorporates many Pascal code fragments that may be used to create more powerful programs.
