I used this book for a 400 level computer graphics course and found it to be very worthwhile. This book provides an introduction to 3D programming using OpenGL. It is not a book on OpenGL programming. The author assumes the reader has a good background in programming, at least senior level in college, and understands the basics of linear algebra such as matrix multiplication, etc. If you are a hobbiest or novice programmer, look for another book. If you are a student of computer science and mathematics, this book is an excellent introduction. Computer graphics is a complex and highly technical topic and any book that tries to hold your hand is probably not worth reading. I would recommend this book to anyone interested in Computer Graphics.
