Google has now officially confirmed that “there’s been a lot of work going on to overhaul Chromium’s graphics system” and that the browser will “begin to take advantage of the GPU to speed up its entire drawing model.”
This is a particle engine I wrote using OpenGL and CUDA to update the particles. You can download it and try it out yourself here
(You need an NVIDIA graphics card, 8 series or newer)
or download the source code and check it out here
(It's fairly well documented, hopefully you can figure it out)
My goal was 750,001 particles, I am running over 12 million here.
A forum member on Chinese website has leaked a 3D Mark Vantage Extreme benchmark, alongwith a GPU-Z screenshot, alleged to be from a next-gen ATI Radeon HD 6870.
Less than half year after the revolutionary appearance of OpenGL 4 we now have OpenGL 4.1.The new update concentrates on Shader Model 5.0 class GPUs and extensions and the desktop version of the specification is now downward compatible with its embedded brother OpenGL ES. In this article I would like to present the features introduced with the latest revision of the OpenGL 4.1 specification.
Reductions, which take a vector of data and reduce it to a single element, are widely used in data-parallel programming. In this article, we examine strategies 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.

This paper introduces a new approximation algorithm for the near-field ambient occlusion problem. It combines known pieces in a new way to achieve substantially improved quality over fast methods and substantially improved performance compared to accurate methods. Intuitively, it computes the analog of a shadow volume for ambient light around each polygon, and then applies a tunable occlusion function within the region it encloses. The algorithm operates on dynamic triangle meshes and produces output that is comparable to ray traced occlusion for many scenes. The algorithm's performance on modern GPUs is largely independent of geometric complexity and is dominated by fill rate, as is the case with most deferred shading algorithms.
Understanding how Direct3D interacts with resources and the command buffer can simplify your engine, enable cross-platform abstractions, and improve performance.
This presentation dispels myths about Direct3D on Xbox 360 and describes a lower-level, engine-friendly approach to managing resources and submitting the scene.
PixelLight is an open-source, cross-platform 3D application framework written in C++. It currently supports Windows and Linux, and a mobile port for Maemo 5 is on the way. PixelLight has a highly plugin driven architecture with plugins for many third-party middleware such as sound and physics engines, input devices etc. It has a modern deferred shader renderer and currently supports both OpenGL and OpenGL ES 2.0.
Now to the interesting part, some technical details of what can be seen on the screenshots:
- OpenGL renderer (OpenGL 1.1 + extensions)
- Horizon Based Ambient Occlusion (HBAO)
- HDR rendering with Reinhard tone mapping, automatic light adaptation and bloom
- Gamma correction
- Shadow mapping
- Volumetric light scattering (nearly no visual impact within the shown screenshots) and depth fog
- Material features like diffuse and opacity mapping, normal mapping, parallax mapping, two sided lighting, specular and gloss mapping, emissive mapping, glow mapping, fresnel reflection, environment mapping... just the usual must-have stuff for modern 3D engines nowadays
On www.pixellight.org you'll find some videos, downloadable demos, an SDK for Windows and Linux and of course the URL of our public git repository.
