VDPAU (Video Decode and Presentation API for Unix) allows Linux systems to offload portions of video decode to the GPU. The resulting video can be post-processed with OpenGL, CUDA, or both. Watch Stephen Warren from NVIDIA explain VDPAU and demonstrate OpenGL texturing of hardware-decoded video frames. Slides (PDF) are also available.
After the success of the first seven entries to the ShaderX book series, of GPU Pro and the soon to be released GPU Pro 2, we are looking for authors for GPU Pro 3. The upcoming book will cover advanced rendering techniques that run on the DirectX or OpenGL run-times, or any other run-time with any language available. It will include topics on: Geometry Manipulation; Rendering Techniques; Handheld Devices Programming; Effects in Image Space; Shadows; 3D Engine Design; Graphics Related Tools; Environmental Effects and a dedicated section on General Purpose GPU Programming that will cover CUDA, DirectCompute and OpenCL examples. Proposals are due by March 17th, 2011. Contact details, an example proposal, writing guidelines and a FAQ can be downloaded from gpupro3.blogspot.com.
After receiving feedback from AMD, G-Truc has written a follow-up article to his original post on the current status of OpenGL 4.1 drivers.
The nopper.tv website now contains one more OpenGL 3.3 and one OpenGL 4.0 example. The OpenGL 4.0 example is a simple tesselation implementation. There are now 13 different OpenGL source code examples available.
Currently there are several ways to feed data to the GPU no matter of what API we use and what type of application we develop. In case of OpenGL we have uniform buffers, texture buffers, texture images, etc. The same is true for OpenCL and other compute APIs that even provide more fine-grained memory management taking advantage of the local data store (LDS) available on today’s hardware. In this article I’ll present the memory access performance characteristics of AMD’s Evergreen-class GPUs focusing on what this all means from OpenGL point of view. While most of the data is about the HD5870, the general principles and relative performance characteristics are valid for other GPUs, including ones from other vendors.
Only a few days since AMD released Catalyst 10.10a, they have released Catalyst 10.10c Hotfix with beta support for OpenGL 4.1. NVIDIA also recently released drivers for OpenGL 4.1. See how each driver does on G-Truc's website.
At the GPU Technology Conference in San Jose on Monday, September 20th, join Mark Kilgard for a pre-conference tutorial on NVIDIA's OpenGL support. Mark will discuss and demonstrate features of OpenGL 4.1 including programmable tessellation.
Skew Matrix Software is pleased to announce new releases of three open-source projects to support software development with the OpenGL-based OpenSceneGraph (OSG) toolkit. OSG can also support COLLADA following the build instructions here.
A series of Windows OpenGL 3 tutorials and articles from beginning to advanced is available online. These tutorials and articles are presented in German.
The 2010 GPU Technology Conference will run from September 20th - 23rd at the San Jose Convention Center. Pre-conference tutorials will include OpenCL optimization techniques and an introduction to OpenCL. The latest OpenGL features will discussed along with NVIDIA specific extensions. A fifty minute talk on WebGL will introduce this newly emerging standard and help you get started in WebGL development.
