Title: I hate bad textbooks
Review: I am using this textbook in a Computer Animation course I am taking. During the course of most of the assignments, I found myself asking "is equation X correct?" It turned out that I was making a subtle mistake, but having to wonder about whether or not there is a mistake in the book is the problem. For example, if the book had made some attempt to explain the equation or where it came from, I might have asked, "What did I do wrong, because it's obvious the equation is correct."This book isn't all bad, though. It does contain lots of useful information. It is perhaps a decent reference book, but I didn't find it very useful for learning the concepts.
Is the review positive or negative?
