The Khronos Group on Thursday announced the release of the OpenGL 4.0 specification that brings the very latest in cross-platform graphics acceleration and functionality to personal computers and workstations and the OpenGL standard serves as the basis for OpenGL ES, the graphics standard on virtually every shipping smart phone.  The new standard supports numerous innovations of DirectX 11 as well as some GPGPU features.

“OpenGL 4.0 continues the ARB’s schedule-driven roll-out of new functionality, and this significant major release enables developers to access leading-edge GPU functionality across multiple platforms with full backwards compatibility,” said Neil Trevett, president of the Khronos Group and vice president at Nvidia.

OpenGL 4.0 further improves the close interoperability with OpenCL for accelerating computationally intensive visual applications.  OpenGL 4.0 also continues support for both the Core and Compatibility profiles first introduced with OpenGL 3.2, enabling developers to use a streamlined API or retain backwards compatibility for existing OpenGL code, depending on their market needs. OpenGL 4.0 has been specifically designed to bring significant benefits to application developers, including:

  • Two new shader stages that enable the GPU to offload geometry tessellation from the CPU;
  • Per-sample fragment shaders and programmable fragment shader input positions for increased rendering quality and anti-aliasing flexibility;
  • Drawing of data generated by OpenGL, or external APIs such as OpenCL, without CPU intervention;
  • Shader subroutines for significantly increased programming flexibility;
  • Separation of texture state and texture data through the addition of a new object type called sampler objects;
  • 64-bit double precision floating point shader operations and inputs/outputs for increased rendering accuracy and quality;
  • Performance improvements, including instanced geometry shaders, instanced arrays, and a new timer query.

The OpenGL 4.0 specification has been defined by the OpenGL ARB (Architecture Review Board) working group at Khronos, and includes the GLSL 4.00 update to the OpenGL Shading language in order to enable developers to access the latest generation of GPU acceleration with significantly enhanced graphics quality, acceleration performance and programming flexibility.

Khronos has also simultaneously released an OpenGL 3.3 specification, together with a set of ARB extensions, to enable as much OpenGL 4.0 functionality as possible on previous generation GPU hardware; providing maximum flexibility and platform coverage for application developers.

“Nvidia is pleased to announce that its upcoming Fermi-based graphics accelerators will fully support OpenGL 4.0 at launch,” said Barthold Lichtenbelt, OpenGL ARB working group chair and senior manager Core OpenGL at Nvidia.

“AMD sees the release of OpenGL 4.0 as another major accomplishment for the OpenGL ARB. AMD contributes to the Khronos workgroups, and we consistently find that Khronos is successful at developing healthy, thriving, and evolving open standards such as OpenGL and OpenCL,” said Ben Bar-Haim, vice president of design engineering at AMD.

Looks like the shoe's on the other foot it's funny since Ati has been making such a big stink about DX11. More funny though is Ati calling PhysX a closed API when it's really middle ware, but DX11 on the other hand is as closed a API as it gets where as OpenGL 4.0 is not. This should shut up a few Ati fanatics for a couple minutes or so.

Bro, you're living in a dream world. lol. PhysX is middle ware?? hahaha. Currently no other application is so closed and not open as your PX. Even MS known for it's conservatism, listen to both ATI and nvidia when they developed DX11. On the other hand, all cards from AMD (5xxx series) will fully support OGL4.0 when this will be released.

Hey Nvidia Fanboy. Could you piss off and go troll on nvidias own boards. Open source is the way forward.
