A book for those interested in how modern graphics programs work and how they can generate realistic-looking objects. It emphasises the mathematics behind computer graphics, most of which 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, CRTs, antialiasing, animation, colour, perception, polygons, compression. With its numerous illustrative examples and exercises, the book is ideal for a two-semester course for advanced undergraduates or graduates, while also making a fine reference for professionals in the field.
