Comment On This Article

The Khronos Group has publicly delivered the specification to OpenGL 2.1. OpenGL 2.1 specification has also been approved by the OpenGL Architecture Review Board. OpenGL 2.1 appends Pixel Buffer Objects for fast texture and pixel copies between frame buffer and buffer objects in GPU memory, texture images specified in standard sRGB color space for enhanced application color management flexibility, and numerous additions to increase the flexibility of shader programming including non-square matrix support, support for arrays as first-class objects, a fragment position query in shaders using Point Sprites, and an invariant attribute for variables to enhance shader code reliability. OpenGL 2.1 continues to be backward compatible with OpenGL programs written for previous versions. The press release (with link to 2.1 specification) can be found in the Khronos Press Release.
