Ray tracing comes to more games thanks to new software tools

Posted on by
You haven't seen much ray tracing in games due in part to the limited frameworks for it. Outside of Microsoft's DirectX, creators have usually had to lean on proprietary approaches. Soon, though, it might be relatively ubiquitous. The Khronos Group...

OpenCL 2.0 provisional spec gets outlined, OpenGL 4.4 released

SIGGRAPH has only just begun, but the Khronos Group is already giving folks of the graphics programming persuasion some fresh APIs to talk about. Yesterday marked the release of the OpenCL 2.0 provisional specification, and it's boasting an Android installable client driver extension, along with improvements to image handling, shared virtual memory and more. It's expected that the new version of OpenCL will be finalized in six month's time, and feedback regarding the changes are being welcomed. The fresh OpenGL 4.4 spec revamps everything from shaders to asynchronous queries while keeping full backwards compatibility, and includes additional functions to make porting Direct3D apps a smoother process. If parallel programming and cross-platform graphics are your thing, hit the break for the full feature breakdown in the press release.

OpenGL ES 3.0 and OpenGL 4.3 squeeze textures to the limit, bring OpenVL along for the ride

OpenGL ES 30 and OpenGL 43 squeeze textures to the limit, bring OpenVL along for the ride

Mobile graphics are clearly setting the agenda at SIGGRAPH this year -- ARM's Mali T600-series parts have just been chased up by a new Khronos Group standard that will likely keep those future video cores well-fed. OpenGL ES 3.0 represents a big leap in textures, introducing "guaranteed support" for more advanced texture effects as well as a new version of ASTC compression that further shrinks texture footprints without a conspicuous visual hit. OpenVL is also coming to give augmented reality apps their own standard. Don't worry, desktop users still get some love through OpenGL 4.3: it adds the new ASTC tricks, new visual effects (think blur) and support for compute shaders without always needing to use OpenCL. All of the new standards promise a bright future in graphics for those living outside of Microsoft's Direct3D universe, although we'd advise being patient: there won't be a full Open GL ES 3.0 testing suite for as long as six months, and any next-generation phones or tablets will still need the graphics hardware to match.

ARM claims new GPU has desktop-class brains, requests OpenCL certificate to prove it

ARM claims new GPU has desktopclass brains, requests OpenCL certificate to prove it

It's been a while since ARM announced its next generation of Mali GPUs, the T604 and T658, but in the semiconductor business silence should never be confused with inactivity. Behind the scenes, the chip designers have been working with Khronos -- that great keeper of open standards -- to ensure the new graphics processors are fully compliant with OpenCL and are therefore able to use their silicon for general compute tasks (AR, photo manipulation, video rendering etc.) as well as for producing pretty visuals.

Importantly, ARM isn't settling for the Embedded Profile version of OpenCL that has been "relaxed" for mobile devices, but is instead aiming for the same Full Profile OpenCL 1.1 found in compliant laptop and desktop GPUs. A tall order for a low-power processor, perhaps, but we have a strong feeling that Khronos's certification is just a formality at this point, and that today's news is a harbinger of real, commercial T6xx-powered devices coming before the end of the year. Even the souped-up Mali 400 in the European Galaxy S III can only reign for so long.
