OpenGL 2.1

OpenGL 2.1 was released on August 2, 2006 and is backward compatible with all prior OpenGL versions. OpenGL 2.1 incorporates the following functionality:

  • Shading Language revision 1.20 (GLSL)
  • to specify and query non-square matrix uniforms for use with the OpenGL Shading Language
  • Pixel buffer objects for efficient image transfers to and from buffer objects for commands such as glTexImage2D and glReadPixels.

This functionality corresponds to the ARB_pixel_buffer_object extension.

  • sRGB texture formats.

This functionality corresponds to the EXT_texture_sRGB extension.
