1.12. Further Information
The Web site http://opengl.org has the latest information for the OpenGL community, forums for developers, and links to a variety of demos and technical information. OpenGL developers should bookmark this site and visit it often.
The standard reference books for the OpenGL API are the OpenGL Programming Guide, Fifth Edition (2005) and the OpenGL Reference Manual, Fourth Edition (2004), both by the OpenGL Architecture Review Board. Another useful OpenGL book is OpenGL SuperBible, Third Edition, by Richard S. Wright, Jr. and Benjamin Lipchak (2004).
A good overview of OpenGL is provided in the technical paper "The Design of the OpenGL Graphics Interface" by Mark Segal and Kurt Akeley (1994). Of course, the definitive document on OpenGL is the specification itself, The OpenGL Graphics System: A Specification, (Version 2.0), by Mark Segal and Kurt Akeley, edited by Jon Leech and Pat Brown (2004).
The OpenGL.org Web site, http://opengl.org, is also a good source for finding source code for OpenGL example programs. Another useful site is Tom Nuyden's site at http://delphi3d.net. The hardware vendors that support OpenGL typically provide lots of example programs, especially for newer OpenGL functionality and extensions. The SGI, NVIDIA, and ATI Web sites are particularly good in this regard.
