SIGGRAPH 2011: OpenGL, WebGL and other developments
Version 4.2 of the OpenGL graphics programming interface is complete, and progress is being made on WebGL and OpenCL. At three "Birds of a Feather" meetings on OpenGL, WebGL and OpenCL, representatives of AMD, NVIDIA, Google and Opera talked about the state of development and future plans.
The main changes concern the official release of version 4.2 of the OpenGL graphics programming interface. Now, OpenGL shaders ("programs") can have side effects instead of just generating vertices and colouring pixels. In particular, shaders can write into any area of a texture, similar to "RWTexture" in DirectX. Atomic counters can be used, for example, to collect pixels for transparency calculations in lists, like the "interlocked" function in DirectX.
In time for the presentation, graphics card manufacturers AMD and NVIDIA published drivers compatible with OpenGL 4.2. The NVIDIA drivers are under development and AMD’s are still at beta status. Windows, Linux, Solaris and FreeBSD versions of the NVIDIA driver are available. For AMD, just Windows and Linux drivers are available.
