当Microsoft变的越来越懒惰的时候, 就像在移动领域 DirectX也开始变得不是很收欢迎. 反面来说游戏开发商开始转向更加开放性能更好的 OpenGL OpenAL 和 OpenCL上. 而越来越多的厂商看好Mac的发展所有选择可夸平台的引擎是百好无一害的事情.
而在苹果的Snow Leopard中将采用OpenCL进行联合运算 而Open GL ES用于iPad 和 iPhone中.
今天OpenGL 4.0全新标准已经问世, 这是向DirectX开启的第一炮.
4.0 对于用户来说有很多好处, 比如低功耗处理性能等. 目前的游戏会让你很快烧掉你的钱这也是微软与游戏厂商的暗暗决定. 而OpenGL是一个完全开放的平台会利用目前的硬件来发挥最好的效果.同时 OpenGL 最强大的就是可以轻松的引入GPU CPU联合计算能力 这也将为mac用户日后的系统体验更上一层.

[QUOTE]March 11, 2010 – San Francisco, GDC 2010 – The Khronos™ Group today announced the release of the OpenGL® 4.0 specification; a significant update to the most widely adopted 2D and 3D graphics API (application programming interface) that is used on all major desktop operating systems. OpenGL 4.0 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 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. This new release continues the rapid evolution of the royalty-free OpenGL standard to enable graphics developers to portably access cutting-edge GPU functionality across diverse operating systems and platforms. The full specification is available for immediate download at http://www.opengl.org/registry.
OpenGL 4.0 further improves the close interoperability with OpenCL™ for accelerating computationally intensive visual applications. OpenGL 4.0 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.
Lastly, Khronos has 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. The full OpenGL 3.3 specification is also available for immediate download at http://www.opengl.org/registry
“AMD sees the release of OpenGL 4.0 as another major accomplishment for the OpenGL ARB,” said Ben Bar-Haim, vice president of design engineering at AMD. “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.”
“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 continues to be a keystone in Khronos’ API ecosystem through driving innovation into OpenGL ES and WebGL™ to bring high-performance programmable graphics to mobile platforms and the Web, and by interoperating with OpenCL to create a seamless visual and compute platform for application developers.”
Learn about OpenGL at Game Developer Conference March 11-13, 2010
Attend this session to learn about the latest updates on the OpenGL standard, and how the OpenGL ARB is addressing the latest graphics hardware capabilities. Also discover how WebGL is bringing OpenGL based graphics to browsers on any platform supporting the OpenGL or OpenGL ES standards, without the need for any plug-in. Additionally, Khronos is offering sessions on OpenCL, COLLADA, and Khronos Mobile APIs.
All Khronos GDC Sessions are in Room 123, North Hall, Moscone Center, San Francisco:
OpenCL Thursday, March 11 1:30pm – 2:30pm
OpenGL featuring WebGL Thursday, March 11 3:00pm – 4:00pm
COLLADA featuring WebGL Friday, March 12 1:30pm – 2:30pm
Mobile featuring WebGL Friday, March 12 3:00pm – 4:00pm
About The Khronos Group
