Voreen 2.5 utilizing OpenGL and GLSL adds support for OpenCL
The new release of the Voreen 2.5 volume rendering engine contains several new features. It is now possible to create and edit animations, which can be exported as videos. Furthermore, Voreen now contains a GPU-based multi-volume renderer, allows aggregation of subnetworks and supports iterative processing by exploiting loops in the network graph, and contains support for OpenCL used for some processors.
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.
Tech Soup announces open registration for its next OpenSceneGraph
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.
GPU Caps Viewer 1.8.9 Available with Better OpenCL Support
The new version of GPU Caps Viewer is available with the support of OpenGL 4.1 context and a better support of OpenCL. Now you can select the GPU that will be used to execute the kernels of the OpenCL demos. GPU Caps Viewer is an information utility focused on the OpenGL, OpenCL and CUDA API level support.
OpenCL and OpenGL presentations slides from SIGGRAPH BOFs available online
Did you miss either the OpenCL BOF or the OpenGL BOF at SIGGRAPH? You can now view the presentation slides online. Included from the OpenCL BOF is the Overview with Neil Trevett, Rendering the Breeze with Graphic Remedy, Intel and OpenCL and Optical Flow with NVIDIA. The following presentations are available from the OpenGL BOF: What's new with OpenGL 4, GLSL 4 tips and tricks, an Ecosystem update, Graphics benchmarking goes to 11, and Mixed OpenGL and OpenCL debugging and profiling using gDEBugger.
SIGGRAPH Day 2: OpenGL BOF today!
The Khronos Group has just one BOF today. The much anticipated OpenGL BOF at 5:15pm at the Wilshire Grand Hotel in the "Los Angeles" room. Jon Peddie from Jon Peddie Research will be opening the BOF followed by Barthold Lichtenbelt–What's new with OpenGL 4, Bill Licea-Kane–GLSL 4 tips and tricks, Jon Leech–OpenGL Ecosystem update, Ian Wiliams–Graphics benchmarking goes to 11 and Yaki Tebeka from Graphic Remedy. Prizes to be won based on OpenGL trivia include:
- 5 SuperBible 5th Edition–Pearson (Addison-Wesley)
- 1 Quadro Graphics Card–NVIDIA
- 1 ATI FirePro V5800 workstation GPU–AMD
- 3 gDEBugger GL one-year license–Graphic Remedy
Yesterdays OpenCL BOF was standing room only, so be sure to arrive early to get a seat! We look forward to seeing you there!
Khronos Drives Evolution of Cross-Platform 3D Graphics with Release of OpenGL 4.1 Specification
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
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!
OpenCL Marching Cubes example implementation using OpenGL
CMSoft brings a versatile and useful tool, Marching Cubes, adapted to GPU acceleration using OpenCL. Sample source code is available. Marching Cubes is an algorithm used in a very wide range of applications, including Medical visualizations such as CT and MRI scan images; Special 3D effects and 3D modelling of metaballs or metasurfaces: Analysis of oil reservoirs in the oil and gas industry and Reconstitution of surfaces whose data has been acquired through seismic methods.
