OpenCL on the Fast Track

Oct 31, 2008 | Categories: General | Developers | Comments

HPCwire has posted a blog on the fast paced OpenCL efforts underway at the Khronos Group. Version 1.0 of OpenCL is currently scheduled to be released in early December at SIGGRAPH Asia 2008 in Singapore. “If they succeed, that’s got to be some kind of industry spec development record—basically from prototype to final in 6 months” wrote Michael Feldman, editor of HPCwire. Khronos will be presenting an OpenCL technical briefing and reception at SC08 on Monday, November 17. Anyone who is interested can attended at no charge. Appetizers and cold beer will be provided!

OpenGL Mathematics (GLM) 0.8.1 released

Oct 31, 2008 | Categories: Developers | Comments

The new version of GLM has been released. GLM is a platform independent C++ mathematics library for 3D software based on the OpenGL Shading Language. Furthermore, GLM provides optional extended feature such as quaternion, transformations, matrix inverse, etc. This release has been developed against GLSL 1.3 specification.

OpenGL Shell v.0.3 available as open source

Oct 31, 2008 | Categories: Applications | Comments

OpenGL Shell is an open source and cross-platform OOP-based wrapper around OpenGL and NVIDIA Cg C-based APIs. The goal of wrapper is to provide abstraction over numerous GL calls, window-system differences and GLSL/Cg shaders. With wrapper it is possible to write managed code, using smart pointers to avoid memory leaks, which impossible with ‘pure’ OpenGL. Now library supports OS Windows XP/Vista and Linux as well.

Cg Toolkit 2.1 Released

Oct 30, 2008 | Categories: Developers | Comments

The Cg Toolkit provides a free cross-platform shading language compiler and runtime API for programmable shading. Write your shader once and deploy it to any API or platform. Cg Toolkit compiles Cg shaders and CgFX effects to OpenGL assembly extensions, GLSL, DirectX 9 assembly, HLSL9, and DirectX 10’s HLSL10. Cg Toolkit supports Linux, Windows, Mac OS X, and Solaris.

Voreen Volume Rendering Engine 1.5 available as open source - uses OpenGL and GLSL

Oct 30, 2008 | Categories: Applications | Comments

The Voreen 1.5 volume rendering engine is now available as open source. Voreen exploits OpenGL as well as GLSL to allow easy and flexible high-performance volume ray-casting on the GPU. Results and programming tutorials available on the website. The goal of the Voreen project is to develop an open source volume rendering engine which allows interactive visualization of volumetric data sets by allowing high flexibility when integrating new visualization techniques.

NVIDIA posts NVISION 2008 presentations on OpenGL, OpenGL 3.0, Cg, and CUDA

Oct 30, 2008 | Categories: Developers | Comments

NVIDIA has posted slides from the joint NVISION 2008 presentations on OpenGL, OpenGL 3.0, Cg, and CUDA. This four part set covers OpenGL and the Future, GeForce 8 Features for OpenGL, Cg 2.1 - “C for Graphics” for All 3D APIs and Platforms and finally OpenGL and CUDA. The presentation was made by Michael Gold, Mark Kilgard, and Barthold Lichtenbelt of NVIDIA.

Tribal Trouble 2 now browser based hardware accelerated using OpenGL

Oct 29, 2008 | Categories: Applications | Comments

The sequel of the cross-platform OpenGL based RTS game Tribal Trouble has been transformed into a game that launches directly from the browser. While taking advantage of the extensive possibilities of a browser for displaying all the quests, missions and expansions, the game doesn’t settle for traditional flash-style gaming integrated in the website, but launches a fully hardware accelerated 3D window using OpenGL, in fullscreen. A standard Java browser plugin is required as our implementation uses the Lightweight Java Game Library (LWJGL).

OpenCL Technical briefing and Reception at SC08

Oct 28, 2008 | Categories: Developers | Comments

OpenCL is an open, royalty-free standard being created by the Khronos Group for programming heterogeneous parallel computing across GPUs and CPUs. OpenCL is being driven by industry-leading companies including AMD, Apple, ARM, Codeplay, Ericsson, Freescale, Imagination Technologies, IBM, Intel, Nokia, NVIDIA, Motorola, RapidMind and Texas Instruments. This informal gathering will provide one of the first opportunities for the HPC community to gain an insight into the architecture and direction of this exciting development. Please register early as seating is limited - we look forward to seeing you in Austin!

Ogre Technologies announces Glux - an OpenGL Utility & Auxiliary Library

Oct 28, 2008 | Categories: Developers | Comments

Ogre Technologies has announced Glux; The OpenGL Utility & Auxiliary Library. It aims to be a more up-to-date replacement for Glux. It is also written in C++, making it not accessible for C users, however. Ogre Technologies mentions that Glux is in a very early stage and only has support for Windows at this time, but will support other OS’ (such as Linux, Mac OS, Mac OS X, ...) in the future. Glux should take care of windowing in your OpenGL applications and also offers some extra functions.

Intel and Yahoo Widget Channel STB based on OpenGL 2.0 technology

Oct 27, 2008 | Categories: General | Comments

IDF in Taipei showed first working demo of Intel’s and Yahoo’s efforts on the Widget Channel front. On display during the keynote was a set-top-box made by GIGABYTE. This box is capable of playing back both 720p and 1080p video with its onboard H.264, VC-1 and MPEG2 hardware decoder. Its GUI is based on OpenGL ES 2.0 technology.

  • Now allows rendering to a FBO with mixed-size attachments
  • VAO bug fixes and performance improvements
  • EXT_texture_swizzle support
  • Transform feedback missing functionality is implemented
  • Various other bug fixes

Details and driver downloads are here.

Hybrid Rendering with CUDA and OpenGL

Oct 22, 2008 | Categories: Developers | Comments

Ray tracing researchers David Luebke and Steven Parker discuss hybrid ray tracing and rasterization rendering techniques that combine CUDA and OpenGL. OpenGL is used for buffer and texture setup. CUDA does the ray tracing. And then OpenGL does post-processing and display.

Driving Ultra High Resolution Displays with OpenGL

Oct 14, 2008 | Categories: Developers | Comments

Ian Williams explains in this presentation how to drive ultra high-resolution displays. Ian discusses OpenGL quad-buffered stereo, the newly published WGL_NV_gpu_affinity extension for GPU affinity when driving multiple GPUs concurrently, and how to configure OpenGL swap groups to coordinate the buffer swaps of multiple GPUs with the NV_swap_group extension.

gDEBugger Tutorial is Now Available

Oct 14, 2008 | Categories: Developers | Comments

Graphic Remedy is proud to announce the release of the gDEBugger tutorial. The new gDEBugger Tutorial supplies all the information needed to start working with gDEBugger; installation and project creation, basic functionality and a great number of tasks that can be performed with gDEBugger. The tutorial explains, in clear and simple language illustrated by screenshots, how to make use of gDEBugger’s features to their full extent, whether the task is general as cleaning up OpenGL usage or more advanced as locating graphic pipeline bottlenecks or redundant state change function calls. The gDEBugger tutorial is available here. It will be included in future versions of gDEBugger.
