The basic principles for the design, use, and understanding of computer-graphics systems and applications are presented in this third edition, along with OpenGL programming examples. Both software and hardware components of graphics systems are thoroughly discussed, and an integrated approach is used to relate two-dimensional and three-dimensional graphics topics. Assuming no background in computer graphics, the authors build on fundamental concepts to show how to create pictures ranging from simple line drawings to highly complex photo-realistic scenes.
