How to use the Windows OpenGL extension mechanism to access OpenGL extensions (328303)
The information in this article applies to:
- Microsoft Platform Software Development Kit (SDK) 1.0
- Microsoft Windows XP Professional
- the operating system: Microsoft Windows XP 64-Bit Edition
This article was previously published under Q328303 SUMMARY
With the OpenGL extension mechanism, OpenGL applications can access non-standard OpenGL functions that may be implemented by the OpenGL vendor or by the video driver vendor.
These functions can be new OpenGL functions that are not implemented in the standard OpenGL library, or, they can be functions that extend the capabilities of existing OpenGL functions.
The source of the extension is indicated by the suffix of the extension function (or by the suffix of the extension constant). For example, the suffix WIN indicates a Windows-specific extension, and the suffixes EXT or ARB indicate extensions that are defined by multiple vendors.
This article describes how to access extension functions.
