OpenGL® Extension Registry

Many OpenGL extensions, as well as extensions to related APIs like GLU, GLX, and WGL, have been defined by vendors and groups of vendors. The extension registry is maintained by SGI and contains specifications for all known extensions, written as modifications to the appropriate specification documents. The registry also defines naming conventions, guidelines for creating new extensions and writing suitable extension specifications, and other related documentation.

Unnumbered extensions

These extensions have not yet been assigned numbers, are still under development, or were abandoned (but are kept in the extension registry for reference purposes).
