This web site contains supplementary material for the book OpenGL Shading Language, published by Addison-Wesley. The first edition of this book was published in 2004 and the second edition was published in 2006. Because of the distinctive color of its cover, it is sometimes fondly referred to as the Orange Book.

This web site was developed and is maintained by the author of OpenGL Shading Language, Randi Rost. If you haven't already guessed, my favorite color is orange. Also, if you haven't already guessed, I only update this site sporadically and I don't always answer inquiries immediately. This web site is a spare time project to help the readers of my book and to dabble with current web technology.
