A short tutorial detailing how to Import and Export COLLADA files with C#/.NET.
OpenCL framework to accelerate an EMRI modeling application using the hardware accelerators – Cell BE and Tesla CUDA GPU. The main goal of this work is to evaluate an emerging computational platform, OpenCL, for scientific computation. Results show OpenCL binary on a par with CUDA SDK. Baseline is an AMD Phenom 2.5Ghz CPU.
In this episode of Adventures in OpenCL tutorials, we cover OpenCL context sharing with OpenGL. We make a simple particle system to demonstrate this feature. One of the most important aspects of this feature is the time we can save by doing rendering and calculations on the same memory in the GPU, this means we don’t need to copy data back and forth!
AMD Developer central just released an OpenCL optimization case study on SImple Reductions. Strategies examined for efficiently mapping reductions onto the ATI Radeon™ HD 5870 GPU and AMD Phenom™ II X4 965 CPU. Taking advantage of properties of the reduction being performed, as well as matching the style of reduction to the hardware platform, can result in performance improvements of up to 15x, compared to naive code.
"Into Tomorrow" broadcasts from Siggraph 2010 in Los Angeles, CA. Dave Graveline interviews Neil Trevett from The Khronos Group & NVIDIA. Dave and Neil discuss WebGL and "Pixels in the Palm of your hand" More videos about the Khronos Group can be found on the YouTube Khronos Channel.
AMD has added OpenGL ES 2.0 support in the 10.8 drivers which will allow hardware accelerated WebGL support. The Catalyst 10.8 product is based on a published Khronos Specification, and is expected to pass the Khronos Conformance Testing Process. Current conformance status can be found at www.khronos.org/conformance.
Cédric Pinson has written a short but concise overview of what WebGL is, and where it is going.
Kanzi provides the missing link between today’s leading 3D graphics content creation tools (e.g. 3DS Max, Maya and Softimage) and target devices, now including the Android devices. Artists can easily export their designs from these software packages to Kanzi Tool using COLLADA data format. Kanzi also features a unified pipeline for OpenGL ES 2.0 and OpenGL ES 1.x based 3D graphics.
CMSoft brings an OpenCL accelerated SVM implementation that can be used for general-purpose classification. Support Vector Machine (SVM) is a statistical learning tool considered to be the state-of-the art classifier for many applications today, including medical research and text categorization. Source code is provided showing classification of the MNIST handwritten database.
Phoronix Test Suite Beta 3 adds another handful of Open Computing Language tests for Linux and Mac OS X. Eventually Windows will also be supported. The new test profiles include JuliaGPU, MandelGPU, SmallPT-GPU, and MandelbulbGPU as well an OpenCL test suite has also been added.
