The Khronos Group has released the OpenGL 4.2 specification, bringing the latest graphics functionality to the cross-platform 2D and 3D graphics API (application programming interface).
OpenGL 4.2 integrates developer feedback and continues the rapid evolution of this royalty-free specification while maintaining full backwards compatibility – enabling applications to incrementally use new features, while portably accessing state-of-the-art graphics processing unit (GPU) functionality across diverse operating systems and platforms, says Barthold Lichtenbelt, working group chair of the OpenGL ARB and director of Tegra graphics at Nvidia.
The OpenGL 4.2 specification has been defined by the OpenGL ARB (Architecture Review Board) working group at Khronos, and includes the GLSL 4.20 update to the OpenGL Shading Language. The OpenGL 4.2 specification contains new features that extend functionality available to developers and enables increased application performance.
