With the launch of Snow Leopard this Friday, now is the time to start getting revved up for some of the new technologies coming with this release. One of them, OpenCL. MacResearch.org has done a great overview of what OpenCL is and a beginners tutorial on how it works and how to use it.
AMD Architect Benedict Gaster recently wrote an 'Hello World' tutorial providing a simple introduction to OpenCL. "OpenCL is a young technology, and, while a specification has been published, there are currently few documents that provide a basic introduction with examples. This article helps make OpenCL easier to understand and implement."
If you missed the "Beyond Programmable Shading" courses at Siggraph 2009, or you missed Siggraph 2009 altogether, no worries: the course notes and PDF slide presentations are now available online compliments of the Institute for Data Analysis and Visualization at UCDavis University of California. Aaron Lefohn from Intel and Mike Houston from AMD organized these courses which included experts on advanced rendering, graphics hardware, and parallel computing for graphics. Panelists from the Q&A were from DICE, Epic Games, Stanford Univeristy, Chalmers University and MIT.
The Khronos Group will be participating at this years ARM techcon3 conference in Santa Clara on October 23rd. The presentation is scheduled for Friday October 23rd from 3 - 3:45PM in Room 207. Exact details of the talk are forthcoming.
Intel announced that it has acquired RapidMind. RapidMind, a framework for expressing data-parallel computations from within C++ and executing them on multicore processors. RapidMind was founded five years ago to commercialize a University of Waterloo programming system called Sh. RapidMind will continue to sell its platform and support existing customers.
Khronos has posted the Siggraph 2009 COLLADA BOF presentation slides and the OpenGL BOF presentation slides. The OpenGL BOF slides include an overview on OpenGL 3.2, OpenGL ES, WebGL, GLSL and gDEBugger. The COLLADA slides include a COLLADA Conformance overview, COLLADA Vision, Project Wonderland, Sirikata--a next generation open source virtual world--and the COLLADA Contest Winners.
AMD announced it is now offering a free OpenCL™ for CPU beta download as part of the ATI Stream SDK v2.0 Beta Program. The beta will help programmers to more easily develop parallel software programs and take further advantage of multi-core x86 CPUs to accelerate software and deliver a better computing experience. AMD has submitted conformance logs from its Microsoft® Windows® and Linux® CPU beta releases to the Khronos Working Group for certification.
BetaNews has published a well thought out review based on the recent announcement of WebGL. Scott Fulton writes "For three-and-a-half years, the rotating cube corner has pretty much been the 'test pattern' for WebGL. But today's endorsement by the Khronos Group, responsible for OpenGL and OpenGL ES, could catapult this project from virtual stagnation into overdrive." There is also a good comment discussion on going. If you wish to comment directly to the developers of WebGL, you can do so on the Official Khronos WebGL Feedback thread.
The Khronos Group has a nice OpenGL and OpenGL Shader Language Quick Reference Card for OpenGL 3.2 and GLSL 1.5. You can download the OpenGL Quick Reference Card in PDF format today from the Khronos OpenGL spec page.
