Khronos OpenGL ES Registry - The Khronos Group Inc
Khronos OpenGL ES Registry
The OpenGL ES Registry contains specifications of the core API and shading language; specifications of Khronos- and vendor-approved OpenGL ES extensions; header files corresponding to the specifications; and related documentation.
The OpenGL ES Registry is part of the Combined OpenGL Registry for OpenGL, OpenGL ES, and OpenGL SC, which includes the XML API registry of reserved enumerants and functions.

OpenGL ES Core API and Shading Language Specifications and Reference Pages
The current version of OpenGL ES is OpenGL ES 3.2. Specifications for older versions 3.1, 3.0, 2.0, 1.1, and 1.0 are also available below.

API and Extension Header Files
Because extensions vary from platform to platform and driver to driver, OpenGL ES segregates headers for each API version into a header for the core API (OpenGL ES 1.0, 1.1, 2.0, 3.0, 3.1 and 3.2) and a separate header defining extension interfaces for that core API. These header files are supplied here for developers and platform vendors. They define interfaces including enumerants, prototypes, and for platforms supporting dynamic runtime extension queries, such as Linux and Microsoft Windows, function pointer typedefs. Please report problems as Issues in the OpenGL-Registry repository.
In addition to the core API and extension headers, there is also an OpenGL ES version-specific platform header file intended to define calling conventions and data types specific to a platform.
Almost all of the headers described below depend on a platform header file common to multiple Khronos APIs called <KHR/khrplatform.h>.
Vendors may include modified versions of any or all of these headers with their OpenGL ES implementations, but in general only the platform-specific OpenGL ES and Khronos headers are likely to be modified by the implementation. This makes it possible for developers to drop in more recently updated versions of the headers obtained here, typically when new extensions are supplied on a platform.
- <GLES3/gl32.h> OpenGL ES 3.2 Header File.
- <GLES2/gl2ext.h> OpenGL ES Extension Header File (this header is defined to contain all defined extension interfaces for OpenGL ES 2.0 and all later versions, since later versions are backwards-compatible with OpenGL ES 2.0).
- <GLES3/gl3platform.h> OpenGL ES 3.2 Platform-Dependent Macros (this header is shared with OpenGL ES 3.0 and 3.1).
- <GLES3/gl31.h> OpenGL ES 3.1 Header File.
- <GLES2/gl2ext.h> OpenGL ES Extension Header File.
- <GLES3/gl3platform.h> OpenGL ES 3.1 Platform-Dependent Macros (this header is shared with OpenGL ES 3.0).

Khronos Shared Platform Header (<KHR/khrplatform.h>)
- The OpenGL ES 3.0, 2.0, and 1.1 headers all depend on the shared <KHR/khrplatform.h> header from the EGL Registry .
