| Specification Update Policy |
| |
| Khronos-approved extension specifications are updated in response to |
| issues and bugs prioritized by the Khronos OpenGL Working Group. For |
| extensions which have been promoted to a core Specification, fixes will |
| first appear in the latest version of that core Specification, and will |
| eventually be backported to the extension document. This policy is |
| described in more detail at |
| https://www.khronos.org/registry/OpenGL/docs/update_policy.php |
| |
| Status |
| |
| Complete. Approved by the ARB at the 2010/01/22 F2F meeting. |
| Approved by the Khronos Board of Promoters on March 10, 2010. |

| Number |
| |
| ARB Extension #92 |
| |
| Dependencies |
| |
| This extension is written against the OpenGL 3.2 specification (Core |
| Profile). |
| |
| Overview |
| |
| This extension adds three new buffer texture formats - RGB32F, RGB32I, |
| and RGB32UI. This partially addresses one of the limitations of buffer |
| textures in the original EXT_texture_buffer_object extension and in |
| OpenGL 3.1, which provide no support for three-component formats. |
