The Khronos Group, the entity behind the cross platform graphics standard Open GL, has announced the fourth version of the 2D and 3D computer graphics set at the Game Developer Conference in San Francisco. A slew of improvements means that OpenGL is now ready to compete on (almost) equal terms with Microsoft's dominant DirectX 11 platform.
- Version 4 adds the all important support for tessellation thanks to two new stage shaders. These will reduce the load on the CPU by letting the GPU take over geometry tessellation computation.
- Other improvements include "64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality" as well as being able to interoperate better with OpenCL seamlessly to accelerate what OpenGL calls "computationally intensive visual applications" like 3D rendering or games. ...
