A few weeks ago, Google became aware of a security issue with WebGL: shaders could be used to indirectly deduce the contents of textures uploaded to the GPU. As a result, Chrome 13 (and Firefox 5) will no longer allow cross-domain media as a WebGL texture. The default behavior will be a DOM_SECURITY_ERR. However, applications may still utilize images and videos from another domain with the cooperation of the server hosting the media, otherwise known as CORS.
Apples latest release of Final Cut Pro is a ground up rewrite offering lots of GUI changes. The power behind this update lies under the hood. Final Cut Pro X supports 64-bit Cocoa APIs, and takes advantage of the power of GPUs OpenCL and multithreaded operations. The change will be obvious when you look at the Activity Monitor.
AMD's new Radeon HD 6990M is based on the TeraScale 2 unified processor architecture and the Barts GPU core. This is a mobile equivalent to the company's high-end Radeon HD 6990 PCI Express graphics card design and features 1,120 stream processing units, 56 texture units, 128 Z/stencil ROP units, and 32 colour ROP units. AMD has included support for OpenGL 4.1, OpenCL 1.1 and MicroSoft's DirectX 11 and DirectCompute 11. There was no mention of the Thermal Design Point, so it is unclear how much power will be required to run this new chip.
Hardware acceleration is all the rage right now among browser makers: it can speed up everything from animating graphics to laying out all the elements of a Web page. Tapping directly into the hardware at a low level not only speeds things up, it saves precious battery power, too. If you aren't sure what WebCL is all about yet, hop over to cnet where they have written up a well rounded review of this latest Khronos Group API.
ShaderToy is a simple tool for OpenGL developers that lets you edit and display OpenGL ES shader programs on Android phones and tablets. It's a fun toy for learning and experimenting with shaders while on the move. The latest version includes the ability to save and load shaders to the SD card, and load texture images from the gallery.
FixStars today published the FREE version of "The OpenCL Programming Book" on their website. The book is based on The Impress Japan Corporation publication "The OpenCL Programming Book (OpenCL Nyumon) " by Fixstars Corporation. You may also purchase a downloadable PDF version.
Dr. Jon Peddie from Jon Peddie Research has tried to make sense of the recent WebGL security issues raised by various companies. He writes "If we can never expose any graphics drivers to the web - we can never have ANY GPU graphics in the browser - and that’s not going to happen." Jon Peddie was recently named one of the most influential industry analysts, who is frequently quoted in trade and business publications, and contributes articles to numerous publications as well as appearing on CNN and TechTV.
Koji Nishi, Sr Engineer of AMD Japan will talk about the update of OpenCL specification as well as how to begin OpenCL programming using AMD GPUs at the seminar on July 5 (Nagoya) and 6 (Osaka).
AMD gDEBugger is an OpenCL™ and OpenGL debugger and memory analyzer integrated into Microsoft Visual Studio. gDEBugger offers real-time OpenCL kernel debugging, which allows developers to step into the kernel execution directly from the API call that issues it, debug inside the kernel, view all variable values across the different work groups and work items - and all this on a single computer with a single GPU.
