okay content, mediocre presentation
This book provides a reasonable introduction to the field of computational geometry, although the notation is sometimes sloppy and the author frequently makes inconsistent assumptions about the reader. For example, on the first page he refers to a circle as a "one-dimensonial set of points," which although valid from a toplogical perspective is a little confusing in an introductory text. As another example, the first exercise refers to "every point in dP," presumably meaning just the corner points (otherwise the problem would be unsolvable). The book also sets up a lot of irrelevant mathematical definitions that generally obfuscate the presentation rather than clarifying it. Although not prohibitive for the ambitious reader, these needless hindrances are at best a little annoying.Secondly, I must criticize the text's scope, in light of the important role computational geometry has played in modern computer graphics. There is no discussion of clipping, culling, occlusion (e.g. BSP, octree, OBB), or even non-polygon primitives -- important topics arguably more useful to the target audience than e.g. convex hulls (to which over 1/4 of the book's pages are devoted). Regardless, this book (combined with a professor and a course) probably would serve quite well as an undergraduate text. Readers interested in a cookbook of applied graphics algorithms, however, should look elsewhere.
