Computer graphics is a fascinating area of computer science. It is widely used as a tool for visualizing information in a broad variety of fields, including science and engineering, medicine, architecture, and entertainment. Interactive graphics programs let people work with computers in a natural manner: a user can supply information to the program through simple hand movements and receive information back through pictures. Computer graphics is helping to change the way people perceive and use computers, and it is available on even the lowest-cost computers today, making it readily accessible to everyone.
This book teaches the concepts and techniques of computer graphics. It teaches people how to write programs that produce graphical pictures and images of many kinds of information. It is designed as a text for either a one- or two-semester course in computer graphics at the junior, senior, or graduate level. It can also be used for self-study. It is aimed principally for students majoring in computer science or engineering but will also suit students in other fields, such as physics, mathematics, business, and art.
