ARM releases sample implementation of OpenMAX DL

ARM has released a sample implementation of OpenMAX DL, which can be freely downloaded from the ARM website. This is an ANSI C sample implementation of the functions described in the OpenMAX DL v1.0.1 API specification. All of the mandatory DL functions are supplied. None of the optional DLx API functions described in Appendix A of the specification are supplied. This implementation attempts to be as mathematically accurate to the OpenMAX definition as possible, using floating-point code where necessary. It is not intended to reflect the expected performance or code size of an optimized (integer only) implementation.

The OpenMAX DL (Development Layer) standardizes access to a comprehensive set of low-level media processing primitives used extensively in audio, video and imaging applications. As well as general purpose media processing functions, OpenMAX DL also contains APIs specifically targeted for the implementation of codecs such as MPEG-4, H.264, MP3, AAC and JPEG.

ARM is also developing highly optimized OpenMAX DL libraries for the ARMv6 SIMD and ARMv7/NEON architectures, which are being in hand-coded in ARM assembly. These libraries will be available for purchase by silicon vendors who can use them royalty free and redistribute them for use on their silicon. Read More

It runs on runs on all Windows platforms, OSX, GNU/Linux, IRIX, Solaris and FreeBSD operating systems. The new v1.2 adds COLLADA support for both the reading and writing of COLLADA 1.4.1 as .dae files as a core feature. Read More

3D Graphics Made Easier with OpenGL ES for BREW

This article on DevX discusses how the introduction of OpenGL ES for BREW, developers now have access to a state-of-the-art 3D rendering platform thats portable across mobile platforms and devices. The article describes how to get your environment set up for OpenGL ES development in BREW, as well as introduces you to the basic concepts you need in order to get started. Note: there's no support for OpenGL in the base BREW emulator. Instead, you need to download the BREW SDK Extension for OpenGL ES for the BREWSDK. Read More

COLLADA: The game developers’ open source data exchange format

This article gives a brief argument for using COLLADA as an open and non-proprietary standard for 3D data exchange. It then addresses a wide list of FAQ questions regarding the uses of COLLADA, how data is organized, a description of COLLADA physics, and most importantly, that COLLADA is free, with no royalties or license fees for use.

AmanithVG Tech Preview 2 OpenGL API hardware-accelerated vector graphics implementation adds VGU support and extensions

AmanithVG engine is a commercial cross-platform engine for accelerated vector graphics. AmanithVG is entirely built on top of OpenGL (from 1.1 to 2.0, using extensions where available) and OpenGL ES (1.1 and 2.0) APIs. By using the OpenGL API, AmanithVG can provide high quality accelerated vector graphics on any kind of 3D chipset already available on the market, achieving tens of times faster performance than software rasterizers. The new tech preview 2 includes an improved geometric engine, a powerful configuration file (lets you customize the geometric kernel and the rendering engine to for example implement features on a chip without shaders, or with limited texture size and texture units count.) , and a set of extensions for complex blend modes, color ramps, enhance dcaps styles and more. The benchmarks comparing rendering performance to software only implementation are impressive. Check out the new AVI video to see some of the new features and accelerated performance. (Imagine this kind of performance in Flash, Illustrator or PDF!) Read More

New Academic Membership enables leading universities and researchers to participate in the development of open standards mobile technologies

The Khronos Group has officially launched its Academic Members program. This program enables researchers and student from a broad range of fields, to participate in the development of open standards for mobile and desktop media technologies. Schools, universities and research institutions are encouraged to join. Khronos will also be actively working Academic members to develop courseware. MIRALab in Geneva Switzerland is the first to join with a focus on virtual reality projects using COLLADA. Read More

Korean Standard Organization TTA launches project to develop benchmarks for OpenVG performance

The Korean Standard Organization TTA (Telecommunication Technology Association) has launched a project to develop standard benchmarks for scalable vector graphics solutions including OpenVG and SVG. ETRI is a lead in the project. SVG (Scalable Vector Graphics, W3C) and OpenVG (Khronos Group) standards are rapidly being adopted in many devices and applications, but there is no objective benchmark for performance comparison. The new benchmark test will provide objective and standard tests suite to compare performance and features of implementations of vector graphics standards, SVG and OpenVG. Requirements and index for performance evaluation will be collected until the end of 2006. Read More

OpenMAX IL component writers guide for Bellagio open source implementation

Bellagio enables Linux software developers and ISVs to familiarize themselves with OpenMAX IL API and to develop their own OpenMAX components for multimedia codecs and controls. This guide details how developers can build OpenMAX IL components using the Bellagio OpenMAX open source distribution. It is based on Bellagio 0.2, but it is anticipated that some details may change in the future with new project releases. OpenMAX components are written in C but an object-oriented approach has been used to avoid code duplication, so that common OpenMAX functions are implemented in a so-called “base component” and can be overridden by derived components.

NVPerfHUD ES performance tool for handheld GPUs shown at SIGGRAPH

At SIGGRAPH NVIDIA showed NVPerfHUD ES, a new performance tool for handheld GPUs. This is a comprehensive suite of performance tools to help debug and profile OpenGL ES applications by giving you access to low-level performance counters inside the driver and hardware counters inside the GPU itself. The counters can be used to determine exactly how your application is using the GPU, identify performance issues, and confirm that performance problems have been resolved. It works well in conjuction with gDEBugger ES. Read More
