Use the index on the left to choose any OpenGL ES 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.
The man pages are now generated in HTML5 format with imbedded MathML, and rely on MathJax to render mathematical equations on browsers which do not natively support MathML. This should work much better on Chrome, Safari, and other browsers which don't support MathML natively.
However, HTML5 isn't well supported on IE 8 or earlier versions. We recommend you use a more recent browser for viewing the man pages.
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 OpenGL.org technical Wiki pages describing the XML Toolchain and Man Pages for more information.
If you find any inaccuracies or typos in the reference pages, please inform us using the feedback form or using the Khronos Bugzilla (you must first create a Bugzilla account, however).
