NVIDIA releases Fermi-Class Quadro OpenCL 1.1 and OpenGL 4.1 capable

The new NVIDIA Quadro Plex 7000 array, and Quadro 6000, Quadro 5000 and Quadro 4000 GPUs feature the new NVIDIA(R) Scalable Geometry Engines and leverage NVIDIA Application Acceleration Engines (AXE) to enable the world's fastest performance across a broad range of CAD, DCC and visualization applications. Rated at 1.3 billion triangles per second in raw performance, the Quadro 6000 enables users to interactively work with models and scenes that are five times more complex than ever before. All of the new GPUs are built on the latest industry standards such including OpenCL 1.1, OpenGL 4.1, DirectX 11 and DirectCompute. Jon Peddie has posted an indepth review of the new Quadro 5000.

CMSoft Image2D Tutorial utilizing OpenCL

Image2D variables play a very important role in OpenCL because they use the texture caching and samplers of the GPU and thus are very suitable to store large arrays and/or data that has to be accessed very often. CMSoft Image2D tutorial covers how to manipulate Image2Ds and how to reinterpret a vector as a Image2D variable, with useful C99 source code to retrieve vector data from a Image2D.

Khronos invites you to the COLLADA BoF at SIGGRAPH

Thanks to the flexibility of COLLADA being an XML based language, the COLLADA Working Group continues to grow with new members from many diverse disciplines that employ 3D technologies. Many of our members turn to Khronos standards such as COLLADA, OpenGL ES and WebGL to support 3D content that can take advantage of web protocols and the forthcoming HTML5 suite of standards. The synergy between the industry's 3D applications and Khronos standards motivates best-in-class COLLADA coherent products; products that soon will have the potential to operate within native 3D enabled browsers. This summer at Siggraph, we welcome you to join us at the COLLADA Birds of a Feather session on Tuesday, July 27 from 1:00 pm - 3:00 pm in the Los Angeles Convention Center, Room 402A, to hear from some of these members on how they employ COLLADA. You'll also learn more about our current working group efforts and our plans for the future. We hope you will join us!
