Query: Doesn't live up to the hype

I purchased this book based on the description and reviews that I had read. I initially believed that I would be able to finally understand some of the concepts that I had read in other books, but upon opening this book I was faced with confusing explanations of simple concepts. Chapter 2 attempts to explain matrices and the standard concept of rotations. I've seen a better explanation in the openGL redbook. He takes a simple concept and uses the most obscure math terms he can to describe it. If I already didn't have a basic grasp of what he was talking about, I would have been completely lost. Anyone who is looking for a book that explains how to write a 3d engine without dumping a bunch of math on you, this book isn't it. If you already know how to write a 3d engine, you don't need this book. If you don't know how to write one, find another book.
