JBenchmark 239 is a 3D performance benchmark suite for Java Binding for the OpenGL ES API (JSR 239) compatible devices. The new benchmark not only measures Java based OpenGL ES 1.0 and 1.1 application performance, but also lets direct comparison to native OpenGL ES and Java Mobile 3D Graphics (JSR 184) results. As the high performance mobile engines all use OpenGL ES for underlying rendering, these measurements will also help finding bottlenecks in current Java implementations. Read More

Tony Parisi one of the co-creators of VRML, reviews "COLLADA: Sailing the Gulf of 3D Digital Content Creation". Quoting from the review: "...the laser-focus of the COLLADA design team seems to have paid off: the industry now has a common exchange format for game assets, and there is hope yet for developers who would rather spend their time building games than building tools to make games. This clarity of focus on the design comes through in the book as well. ... A detailed and lucid book that explains COLLADA from concept through implementation. If you are a programmer with a reasonable understanding of 3D graphics programming and/or authoring using 3D scene graphs, you will be able to learn the basics of COLLADA. If you are an experienced 3D toolmaker, COLLADA contains everything you need to get up and running to build your game, game engine or content pipeline tool. If you are a manager or decision maker, you get the added comfort of knowing that — finally — you just might be able to write that tool once and not over and over again." Read More

Futuremark Corporation has been selected to create the OpenKODE Conformance Test Suite. The OpenKODE conformance testing tools will enable mobile device chip makers, handset manufacturers and middleware vendors to confirm that their products conform to the OpenKODE 1.0 media stack specification and will include trans-API conformance tests to ensure that OpenKODE implementations support rich mixing of media types such as real-time video being processed in a 3D application. The suite of conformance testing tools will be made available through the Khronos Group OpenKODE Adopters program and products that pass all the tests may use the OpenKODE trademark. OpenKODE 1.0 is expected to be publicly released in the first quarter of 2007. Read More

What is OpenKODE? OpenKODE 1.0 brings together the OpenGL ES and OpenVG Khronos media APIs to provide state-of-the-art acceleration for vector 2D and 3D graphics and provides the new OpenKODE Core API that abstracts operating system resources to minimize source changes when porting games and applications between Linux, Brew, Symbian, Windows Mobile, WIPI and RTOS-based platforms. Subsequent versions of OpenKODE will add the OpenSL ES and OpenMAX media APIs to provide accelerated video and audio that is fully integrated with graphics processing.

The Japanese translation of the COLLADA 1.4.1 specification is now available. You can download the Japanese translation from the COLLADA page as well as access the COLLADA DOM and the RT FX, and Refinery developer tools and code. Read More
GBenchmark v1.0 is 3D performance benchmark suite for OpenGL ES compatible Brew, Linux, Symbian and Windows Mobile devices. The new benchmark not only measures OpenGL ES 1.0 and 1.1 application performance, but also allows direct side-by-sdie comparison of native OpenGL ES and Java (M3G) based mobile 3D implementations. It can also be used to find performance bottlenecks. GLBenchmark is available as free networked-only, corporate and stategic (source code) versions. Check out the latest posted lperformance results.

The presentations from the full day Khronos Media Acceleration Forum in Cambridge UK are now online. These presentations include OpenKODE, a non-technical introduction to OpenGL ES, hardware-accelerated OpenVG, OpenSL ES overview, a technical overview of OpenGL ES 1.1, a technical overview of OpenMAX DL, IL and AL, how shader programmability with OpenGL ES 2.0 can boost overall system level performance, and high-performance 3D graphics coding for handheld devices.

This article describes the impact of hardware accelerated OpenGL ES (from Imagination Technologies) on the quality and performance of graphics on the Sony Ericsson's UIQ 3 phones. The obvious gain is in the quality of 3D graphics, including texture filtering, anti-aliasing and faster drawing. The other important gain is in software performance. With hardware accelerated OpenGL ES, the CPU is only running the phone OS and the game logic and not the the rendering. As a result the CPU can spend more time on the gaming experience; developers can implement more complex game play, improve artificial intelligence and use richer audio effects. Read More
Episode #4 in the Khronos Mobile Media Developer podcast series focuses on OpenMAX DL - a standard to enable rapid porting of codecs to new platforms. OpenMAX DL (Development Layer) APIs contains a comprehensive set of audio, video and imaging functions that can be optimized by platform developers for new CPUs, hardware engines, and DSPs. Developers can then use the APIs to create portable accelerated codec functionality such as MPEG-4, H.264, MP3, AAC and JPEG. They can port the codec to a new platform simply by getting the appropriate platform library.
