An excellent starting point for somebody that knows nothing at all about 3D models, but can only be considered a stepping stone to other books that gloss over the basics.He starts with a good intro to matrices and quaternions, followed by a good intro to modeling concepts, and then describes a few formats in detail. Unfortunately, he doesn't go into any more advanced discussion on how to put things together... i.e. how to *use* the models. A few pages are wasted explaining how to use some basic "C", but I've seen worse...Overall, I give it four stars because, if you know nothing of the topic, it is an excellent jump start. If you do have knowledge of the topic, then you aren't the target audience.
