Version

    Last Modified Date:         December 7, 2009
    Revision:                   2

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.
