OpenGL based ClanLib 2.2.5 toolkit library released

ClanLib is a cross platform C++ toolkit library based around OpenGL. It's primary focus is on games (free or commerical thanks to a BSD style license). Image, Sprite and Font drawing are optimised to give high frame rates by drawing in batches, reducing OpenGL state changes. If OpenGL v2.0 or above is not available, the library seamlessly provides OpenGL v1.3 or a high performance software renderer. Supports multiple windows with a full GUI framework for use in 2D or 3D applications. This latest version contains new examples demonstrating the ease of creating custom shaders. In addition, a HDR test has been updated to demonstrate using OpenGL floating point textures.

Hardware Video Decode and OpenGL Video Texturing for Linux

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.

GPU Pro 3: Call for Authors

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.

UK researchers study GPGPU vs Blue Gene

Researchers from the University of Warwick’s Performance Computing and Visualization Department and Oxford University’s eResearch Centre have put together a study: should we install a GPGPU-based system or a more traditional IMB Blue Gene-like supercomputer? The team’s research will present their work at the 1st International Workshop on Performance Modeling, Benchmarking and Simulation of High Performance Computing Systems at the SC10 conference in New Orleans. The Khronos Group will be at Booth # 1132 at SC10.

Texture and buffer access performance in OpenGL

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.

Copperlicht 1.3.1 released

CopperLicht is a JavaScript 3D engine for creating games and 3d applications in the webbrowser. It uses the WebGL canvas supported by modern browsers and is able to render hardware accelerated 3d graphics without any plugins. This update sees a few bug fixes as well as having its own name space defined in JS to avoid conflicts with other libraries, such as jQuery.
