OpenGL Distilled

7.4. More Information

The definitive resource for OpenGL extensions is the OpenGL Extension Registry Web site, http://oss.sgi.com/projects/ogl-sample/registry/, which provides access to vendor-specific, EXT, and ARB extension specifications. Also, the appendix, "ARB Extensions," of The OpenGL Graphics System, enumerates all ARB-approved extensions, even those that have already been folded into the core specification.

Due to its scope, OpenGL^® Distilled doesn't provide an exhaustive list of features added to each OpenGL version. But The OpenGL Graphics System, Appendices C through I, provides this information.

The book's Web site contains version-safe example code, as well as full source for the Extensions program, which uses the PixelBuffer class in Listing 7-1.
