Description

The third edition of this book continues to focus on the 3D aspects of computer graphics, and reflects the growing demand for real-time applications such as games and virtual reality. It also includes new material on Visualization in Scientific Computing and graphics standards such as PHIGS. It deals with the processes involved in converting a mathematical or geometric description of an object–a computer graphics model–into a visualization–a two-dimensional projection–that simulates the appearance of a real object. Alan Watt provides students with a knowledge of complex and emerging topics in the field of computer graphics, including advances in rendering and new material on animation. This is an appropriate text for a first course on computer graphics at the Junior, Senior or graduate level.
