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.
DMP is proud to announce two all new OpenGL ES programming training courses. OpenGL ES programming training I and II will run September 9-10 and September 16-17 2010. Complete details are available online for the Training I and Training II courses in english, and in Japanese.
The Khronos Group has just one BOF today. The Mobile BOF at 1pm in room 402A LACC. Get the inside track on OpenGL ES, Open VG, Open MAX and all the new media APIs being used to develop the billion-dollar, billion-user gaming and mobile multimedia markets! Featured presentations will be made by ARM, NVIDIA, Hi Corp, Graphic Remedy, Symbio and HUONE.
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.
AMD and NVIDIA are providing some pretty sweet graphics hardware at the OpenCL BOF at SIGGRAPH on Tuesday 27th from 4:00 pm - 6:00, Room 402A in the Los Angeles Convention Center – the prizes include:
- Two Fermi-based NVIDIA Quadro FX 5000 – packed with 2.5GB GDDR5!
- Two Cypress-based ATI Radeon 5870s!
Prizes will be awarded on knowledge of OpenCL “trivia” so come prepared!
The OpenCL CL BOF at SIGGRAPH will be a great place to come up to speed on the new OpenCL 1.1 and interact with key OpenCL developers from AMD, Khronos, Graphic Remedy Intel and NVIDIA – including the OpenCL chair and spec editor – be there or be polygonal.
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.
The Khronos will be at booth #1201 at SIGGRAPH 2010. We hope we will see everyone there. If you plan on joining us for one of our BOFs, please be sure to register to reserve your seat. Please note that the OpenGL BOF has had a room change. The OpenGL BOF is now in the "Los Angeles" Room at the Wilshire Grand Hotel. Complete details can be found on our website.
In todays world of copy paste programming expertise, OpenCL will force you to learn the nuts and bolts of programming. Learn why it is important to learn about the hardware you are programming for.
You are cordially invited to come listen to the latest on OpenGL 4 and more, meet fellow OpenGL enthusiasts and share a free beverage with us. We will also be giving away some awesome prices to the people that are able to quickly answer the sometimes-not-so-trivia questions. Prizes include the new edition of the OpenGL Super Bible, licenses to gDEBugger, an AMD FirePro V5800 workstation GPU and a NVIDIA Quadro workstation board. The OpenGL BOF will be Wednesday, 28 July from 5:15 pm - 7:15 pm in the Wilshire Grand hotel, the Los Angeles room. Reserve a spot, sign up now at the Khronos.org website.
Are you having trouble getting start in OpenCL development. Enj has started a tutorial series aimed at developers trying to learn OpenCL from the bottom up, with a focus on practicality.
