Sentinel Ave LLC, funded by the U.S. Defense Department, has posted a demo of its client software showing the viewer flying through 3D cityscapes with live videos embedded in them. The software, AVE Video Fusion, combines Google Earth-like features with live camera videos projected on a 3D model as noted in a video caption. It is written from scratch using C++ and OpenGL and claims to run on PCs with no custom hardware.
faogen is a fast ambient occlusion generator. Use your video card GPU to compute ambient occlusion really fast. Support both texture and per-vertex calculation. Input scene can loaded from Wavefront OBJ or LightWave 3D object (*.LWO) files (future versions will allow to use more file formats).
Faogen itself uses hardware shadow mapping, floating-point render targets and OpenGL Shading Language to compute ambient occlusion data. This process is much faster than any CPU-based approach.
In AMD/ATI laboratory test, four Radeon HD 4870 X2 have been combined. But AMD will not release any drivers for such an Octa Crossfire bundle. In consideration of a motherboard that would have to be able to bear four dual slot graphics cards and the required scaling, Octa Crossfire should be seen as nothing more than a technical gimmick.
You may have noticed that many hardware and software review websites make sure to note when they use real or synthetic benchmarks in a particular review. Some sites concentrate solely on synthetic benchmarks while others concentrate on the so called “real world” benchmarks. The important thing is not to know which one is right or wrong but to understand what the difference is and what you can personally do with the data that you get from these benchmarks you find online.
maximumpc.com had an opportunity to speak with id co-founder John Carmack after the big EA press conference yesterday (where id surprisingly announced a partnership with EA to publish Rage).
maximumpc.com grilled the legendary game developer (and part-time rocket scientist) about id’s post-apocalyptic shooter, the state of gaming graphics, and what his plans are after id Tech 5.
I think Inno3D does a superb job with their product line. With the 9800 GTX OC edition, Inno3D brought a great product to the market, with the extra game full game you’ll retrieve some additional value. And that coupled with the recent price fall in the NVIDIA GTX series … you really can’t go wrong here and you’ll love playing the latest games with it.

La GeForce GTX 280 confirme qu’elle est bien la carte de tous les superlatifs : la plus grosse, la plus complexe, la plus performante mais aussi la plus encombrante, la plus bruyante, la plus gourmande et surtout la plus chère (de 460 € à plus de 500 €). Des points faibles qui pèsent lourd par rapport aux avantages surtout que la Radeon HD 4870 vient jouer les trouble-fêtes. En effet, si la Radeon HD 4870 est un peu en retrait par rapport à sa rivale, elle est surtout beaucoup moins chère (230 €) et nettement plus discrète. Sa seule contrepartie est une consommation importante au repos. La Radeon HD 4850 (moins de 160 €) est la révélation de ce comparatif : elle ne souffre d’aucun point faible. Ses prestations la mettent en concurrence avec la GeForce 8800 GTS OC MSI ainsi que les GeForce 9800 GTX et GTX+ (220 à 230 €). Ces dernières sont au moins 30% plus chères et nettement plus bruyantes et donc dans l’état actuel des choses sans le moindre intérêt ! Seules les GeForce 8800 GTS 512 Mo peuvent encore tirer leur épingle du jeu en raison d’un prix inférieur à 200 € et un silence de fonctionnement plus qu’appréciable. Particulièrement intéressante à son lancement, la GeForce 9600 GT est aujourd’hui caduque.
TT-Hardware has published a comparative article about GeForce GTX 280 and Radeon HD 4870/4850 performances.
This work describes the implementation of a real-time visual tracker that targets the position and 3D pose of objects (specifically faces) in video sequences. The use of GPUs for the computation and efficient sparse-template-based particle filtering allows real-time processing even when tracking multiple faces simultaneously in high-resolution video frames. Using a GPU and the NVIDIA CUDA technology, performance improvements as large as ten times compared to a similar CPU-only tracker are achieved.
Arauna is a real-time ray tracer developed for game development. Being a real-time ray tracer, it is experimental, and does not yet deliver the performance needed to produce graphics of the same quality as modern games do using a GPU. However, in its class, it is one of the fastest (probably the fastest) renderer. Two games have been developed already using Arauna, both by students of the IGAD program of the NHTV University of Applied Sciences (Breda, The Netherlands).
Tech ARP has updated its graphics cards comparison guide and now 355 desktop graphics cards are covered. This comprehensive comparison will allow you to easily compare 18 different specifications for each and every card.
Version 2.6 of WordPress.org is now available, almost a month ahead schedule. Version 2.6 “Tyner,” named for jazz pianist McCoy Tyner, contains a number of new features that make WordPress a more powerful CMS: you can now track changes to every post and page and easily post from wherever you are on the web, plus there are dozens of incremental improvements to the features introduced in version 2.5.
TUL Corporation’s PCS HD4850 is the world’s first graphics card to offer on-board 2gig video memory. The card is based on RV770 core chip, with 800 stream processors and 2GB of GDDR3 high-speed memory.
Memory size makes a great impact on performance, even a powerful GPU can suffer from bottlenecks due to slow and insufficient video memory. The more the memory buffer, the more the data graphics can be saved – thus eliminating the need to access system memory and providing faster graphical performance.
When it comes to ATI products Sapphire has always offered the most influential graphics cards available, and the new Radeon HD 4870 is no different. For the first time in this industry, we have a fully-functional product equipped with 900 MHz GDDR5 video frame buffer. The Sapphire 100243L model offers 24x custom filter anti-aliasing (CFAA) on its 750 MHz 800-core RV770 GPU. Benchmark Reviews tests the Sapphire Radeon HD 4870 graphics card against the closest competition, and even compare CrossFireX performance in this performance review.
