OpenGL 4.0 announced during GDC

Today, the Khronos Group announced the launch of OpenGL 4.0, the cross-platform 3D & graphics API. OpenGL was most recently at version 3.2. Updated specifications are available at the opengl.org site. Game and 3D developers are presumably salivating.

Mac OS X includes OpenGL, and the iPhone runs an embedded version of OpenGL called OpenGL ES. The mobile ES version remains in its 2.0 release and is expected to move to OpenGL ES 2.1 in the near future.

The updated OpenGL release includes enhanced shaders, better texture support, and 64-bit double-precision floating point operations, amongh other features. It offers support for backwards compatibility with existing OpenGL code."AMD sees the release of OpenGL 4.0 as another major accomplishment for the OpenGL ARB," said Ben Bar-Haim, vice president of design engineering at AMD, in a press release statement.

An OpenGL 3.3 specification has been released simultaneously with the 4.0 spec, "to enable as much OpenGL 4.0 functionality as possible on previous generation GPU hardware".
