OpenGL 3.3 Reference Pages

Use the index on the left to choose any OpenGL reference page for viewing. The reference pages (also known as "man pages") include all of the important usage information for each command. This information includes a description of all parameters, return values, error conditions, and related commands.

Core Context Functionality

These man pages only document the core context. For compatibility context specific functionality, please refer to the OpenGL 2.1 Reference Pages and/or the appropriate extension spec you are interested in using.

Browser Compatibility

Please use the latest version of your brower to view this web-page to ensure the least amount of compatibility issues.

Downloading Man Page Sources

The Docbook XML source for the man pages is available for anonymous checkout in Khronos' Subversion server, and you can build a man page distribution of your own using open source tools. See the technical Wiki pages describing the XML Toolchain and Man Pages for more information.


If you find any inaccuracies or typos in the reference pages, don't hesitate to inform us via the feedback form or using the Khronos Bugzilla (you must first create a Bugzilla account, however).
