Peter Shirley. Fundamentals of Computer Graphics, 2ed
note: the new 2nd edition is considerably different than the first - it is green (not orange).

Most likely, you will get the "uncorrected" 1st printing. If so, please be sure to check the errata page. In fact, I recommend that you go through the book and mark the errata right away.

Mason Woo, et al. The OpenGL Programmer's Guide. This is sometimes known as the "red book."
The current edition is the 5th edition, but for the purposes of this class an older edition would be OK too.
If you don't want to buy this book, the complete contents of the older version (fine for the required class readings) is online in html or pdf.

There will be some readings from this book, and its an important reference.
