Computer Graphics and Geometric Modeling

This is a book for those interested in understanding how graphics programs work and how present-day computer graphics can generate realistic-looking curves, surfaces, and solid objects. The book emphasizes the mathematics behind computer graphics and most of the required math is included in an appendix. The main topics covered are: scan conversion methods; selecting the best pixels for generating lines, circles and other objects; geometric transformations and projections; translations, rotations, moving in 3d, perspective projections; curves and surfaces; construction, wire-frames, rendering, normals; and, CRTs, antialiasing, animation, color, perception, polygons, compression. With its numerous illustrative examples and exercises, the book makes a splendid text for a two-semester course in computer graphics for advanced undergraduates or graduate students. It also serves a fine reference for professionals in the computer graphics field.

Graphics, especially computer graphics, is commonly used in texts, advertisements, and movies to illustrate concepts, to emphasize points being discussed, and to entertain. Computer graphics today is a mature, successful, and growing field.
