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

• Tags:

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.

Tech Soup announces open registration for its next OpenSceneGraph

• Tags:

Tech Soup announces open registration for its next OpenSceneGraph (OSG) course, October 5-7, 2010, in South Lake Union, Seattle, Washington. This class will teach students everything to be proficient in OSG in a 3-day intensive course. This course covers everything developers need to know to take maximum advantage of OpenSceneGraph from intermediate through advanced. We'll also take a tour through VirtualPlanetBuilder so you can build geospecific, tiled, paged datasets. Developers attending the course learn the mechanisms behind effective OSG development from scenegraph creation and manipulation through debugging & optimizing. Through instruction and labs, students build scenes and interact with real code from day one. The course is fast-paced, requires creativity and problem solving, and leaves users with a thorough immersion in OpenSceneGraph. Instruction is hands-on with numerous labs where students directly turn concepts into practical knowledge.

Khronos Drives Evolution of Cross-Platform 3D Graphics with Release of OpenGL 4.1 Specification

• Tags:

The Khronos™ Group today announced the immediate release of the OpenGL® 4.1 specification, bringing the very latest graphics functionality to the most advanced and widely adopted cross-platform 2D and 3D graphics API (application programming interface). OpenGL 4.1 is the sixth update to OpenGL specification in two years, continuing the rapid evolution of this royalty-free specification. This new version continues to maintain full backwards compatibility to enable developers to begin using new features whenever they choose, while portably accessing state-of-the-art GPU functionality across diverse operating systems and platforms. New functionality in the core OpenGL 4.1 specification includes full compatibility with OpenGL ES 2.0 APIs, the ability to query and load a binary for shader program objects to save re-compilation time, the capability to bind programs individually to programmable stages for programming flexibility, 64-bit floating-point component vertex shader inputs for higher geometric precision and multiple viewports for a rendering surface for increased rendering flexibility. The latest specifications can be downloaded today in OpenGL Registry. An official feedback forum is online at the OpenGL Forums.

Khronos invites you to the COLLADA BoF at SIGGRAPH

• Tags:

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!
