Imagination was showing off GPU compute on a cell phone chip at GDC, physics in your pocket. That demo was pretty simple, take a Pandaboard with a TI OMAP 4430, a dual-core ARM A9 CPU and an Imagination SGX540 GPU, and run a cloth simulation on it. Not only could the OpenCL version exploit the GPU to do more balls and sheets than the CPU version, but it saved power while doing so. How much? On one CPU, the simulation took about .68A@5V to run at 14FPS with 100% CPU load. With two A9 cores loaded, the Pandaboard pulled .84A and ran at 24FPS. In OpenCL, CPU load dropped to less than 30%, FPS jumped to 42, and power draw went down to .60A. More than 10% less energy used, 3x the frame rate, and you could run more simulations on the same box if you wanted. Not bad at all.
Vivante Corporation announced that HiSilicon has expanded its ongoing technology partnership to include additional GC (Graphics and Compute) cores. HiSilicon will continue to integrate these key pieces of visual computing IP into SoC products for mobile and consumer products. Access to the latest Vivante IP cores, give HiSilicon an innovative technology platform based on the latest 3D, CGPU (Composition GPU) and GPGPU APIs. The latest agreement enables HiSilicon to deliver the highest graphics performance in products spanning its entire portfolio.
Graphics processor intellectual property licensor Imagination Technologies Group has signed up HiSilicon Technologies Co. Ltd. (Shenzhen, China) as licensee for multiple PowerVR multimedia cores covering graphics, video and display. The license agreement includes a member of the PowerVR Series 6 graphics family known as "Rogue."
The Khronos Group has posted video presentations from Barcelona. Speaking in Barcelona were Neil Trevett, Khronos Group President, Erik Noreke, Kristof Beets from Imagination Technology, Enrica Filippi from ST-Ericsson and Sri Kannan Iyer from ARM. A complete presentation list, photos and video list is also available from the Khronos event page.
Jon Peddie has a great write up on GFX Speak about The Khronos Group turning 12 this year.
Did you miss the WebGL Meetup we held along side GDC last week? No worries, we recorded the entire meetup, and have posted it in four parts on YouTube (part one, two, three) and as podcasts. With Tony Parisi as moderator, the WebGL meetup covered lots of ground, including a spec update, lots of demo's and a security corner with Ken Russell from Google. The slide presentation in PDF format from the meetup is also online.
The Khronos Group was an Augmented Reality forum Platinum sponsor at the 2012 Mobile World Congress this year. Presenting at the forum were ARM, Freescale, Imagination Technologies and ST Ericsson, with Christine Perey as the panel moderator. The slide presentations from those presentations are now available online.
Rightware announced that it will release Android 3D Homescreen Template to radically shorten the development time of 3D user interfaces on Android devices. Rightware's ready-made 3D homescreen design template enables the industry's fastest creation, interaction testing and deployment of photorealistic - and even stereoscopic - 3D homescreens on Android devices. Rightware's Android 3D Homescreen Template is powered by Kanzi UI Solution which has been optimized for the latest CPUs and GPUs to ensure optimal performance. The 3D Homescreen Template is provided with native OpenGL ES support and is capable of powering stereoscopic 3D user interface elements and homescreen entities with extreme swiftness.
Version 0.9.11 of the free open-source, cross-platform 3D application framework PixelLight has been released. We're using OpenGL as well as GLSL within our main-renderer and OpenGL ES 2.0 for Android. Highlight of this release is the new Qt based viewer. This tool makes it possible to inspect complete scenes via the GUI and offers basic edit features for visual debugging. On the renderer side, we've added "Fast Approximate Anti-Aliasing" (FXAA) and support for volume texture compression (VTC).
Learning OpenGL ES is contains a series of tutorials and lessons for Android, focusing on OpenGL ES 2.0. The site has lots of resources, and looks like a promising place to help developers get off to a good start with OpenGL ES and Android.
