Qt Labs Blog is doing a series on Graphics and Performance of Qt. The first of the series is an overview of the whole painter, pixmaps, widgets, graphicsview, backingstore idea. Reasons for using the Khronos family of APIs is included for OpenGL and OpenVG.
Fixstars has announced a beta version of "FOXC" OpenCL Compiler for x86. FOXC will allow software developers to take full advantage of multi-core x86 CPUs to develop OpenCL-based softwares. This is a source-to-source compiler that takes OpenCL code as the input source and the output source file is a readable C code. The "FOXC" Beta version can be downloaded for free from the Fixstars website.
The latest version of the OpenCTM 3D mesh viewer (part of the OpenCTM v1.0.2 SDK) has support for loading, viewing and saving several different file formats (OpenCTM, COLLADA, STL, PLY, OBJ and 3DS), making it a convenient companion tool for 3D graphics developers and artists. The viewer uses OpenGL for its 3D view and GUI, and works under Windows, Mac OS X, Linux, etc. OpenCTM is a file format, software library and a tool set for compression of triangle meshes. It fits well with the current OpenGL rendering pipeline, with support for custom shader attributes among other things.
ALT Software has released optimized OpenGL ES 1.1 and OpenVG 1.1 graphics drivers for Imagination Technologies POWERVR MBX graphics core. The drivers are designed to work on Wind River’s VxWorks and Wind River Linux operating systems.
The Khronos Group announced the unveiling of the WebGL Draft Specification. WebGL is a cross-platform, royalty-free web standard for a low-level 3D graphics API based on OpenGL ES 2.0, exposed through the HTML5 Canvas element as Document Object Model interfaces. Khronos has setup a wiki, forums and a public mailing list for greater community involvement.
AMD announced collaborate with SiSoftware to develope one of the first industry benchmark testing suites for OpenCL. To be released by SiSoftware, the OpenCL GPGPU benchmark suite is part of SiSoftware Sandra 2010. The benchmark suite includes remote analysis, benchmarking and diagnostic features for PCs, servers, mobile devices and networks, and can be used to test OpenCL performance on ATI Stream technology.
DMP is proud to announce two all new OpenGL ES programming training courses. For those who have taken past courses, these are two new courses. OpenGL ES programming training I and II will run January 14-15 and January 21-22 2010. Complete details are available online for the Training I and Training II course in english, or Japanese.
Ben Bergen, evolving applications and architectures team, Los Alamos National Laboratory, commented at SC09 : "Our development experience at Los Alamos National Laboratory with adapting codes to the Roadrunner supercomputing architecture exposed several areas where there were no obvious tools or techniques that would allow us to maintain portability across the variety of platforms that we must routinely support to fulfil the Laboratory’s stewardship mission. Initial proof-of-concept experiments with the OpenCL framework make us optimistic that OpenCL can address many of the challenges that we will be facing as the HPC landscape evolves into the future."
Nokia has released Version 4.6 of its Qt cross-platform application and UI framework. Key performance improvements include an optimized, re-written Qt GraphicsView rendering algorithm, a new OpenGL paint engine and 2D vector graphic support using OpenVG. Qt 4.6 includes support for the Symbian platform for the first time, and adds Windows 7, Apple Mac OS 10.6 (Snow Leopard), and the upcoming Maemo 6 to the list of Qt-supported platforms.
