This is a really good book. One of the other reviewers had given it a poor review because s/he felt that the book was misleading in that it was more about computer graphics than OpenGL. This is very true, but the title of the book is "Computer Graphics using OpenGL." That means that it claims to teach you the subject of computer graphics using OpenGL as its main tool. But, if that title does mislead you, be forewarned that there are much better books at teaching you the OpenGL API.
This book, in my opinion, does a great job covering all the standard topics of computer graphics and leaves you ready to tackle some of the more advanced texts on the subject. I also really appreciated the gentle approach to the mathematics involved. The author has a good appedix to help you brush up on any math-related topics you may be rusty on. Overall, this is a great book and comes highly recommended as a means to start into the field of computer graphics.
