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:

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.
