SGI Announces Demo Challenge

SGI recently announced a contest. The coder of the OpenGL API demo judged best by a panel of judges will receive a $40,000 Onyx4 UltimateVision visualization machine, running IRIX. The contest is open to US and Canadian residents.

The .NET Show: Managed DirectX

DirectX has been providing game developers with a great platform for rich and fast-paced games on Windows for many years. As these platform technologies advance to embrace the concepts of "Managed" programming, DirectX rises to meet the challenge head on.

The Future of 3D Graphics

At last week's WinHEC show, Nvidia Chief Scientist David Kirk pontificated on where 3D graphics rendering is going over the next decade. What can you expect? Photorealistic rendering and cinematic realism, of course. Bottom line -- it's not about pushing clock speeds and pixel rates, but rather making pixels much better looking!

Galaxy Dynamics Computer Simulation

The paper considers a mathematical model of the behavior of an assembly of N stars. The 'Kepler' Microsoft Windows demo application based of this model enables to perform real-time simulation of star clusters dynamics for N~=2500. Such performance rate is possible through the use of the Intel Integrated Performance Primitives (IPP) library. The paper also estimates the efficiency of the IPP application and provides an example of C-code with the IPP functions calls. Computer-simulated images of the spiral galaxy forming process, as well as the real galaxies photos, are presented.

DirectX 9.0 Released

Microsoft DirectX is a group of technologies designed to make Windows-based computers an ideal platform for running and displaying applications rich in multimedia elements such as full-color graphics, video, 3D animation, and rich audio. DirectX 9.0 includes security and performance updates, along with many new features across all technologies, which can be accessed by applications using the DirectX 9.0 APIs.Update: SDK download listing.

ATI Mobility Radeon 9000 Review

AnandTech has reviewed ATI's latest mobile graphics solution. According to the reviewer this small and energy efficient chip is the new king when it comes to mobile graphic chips for notebooks. Also John Carmack is apparently very positive about the chip and also stated that Doom 3 will be able to run smoothly with this new Radeon chip.

Easy Hack to Enable Quartz Extreme on G3s with PCI Graphics Cards

It is possible to easily enable Quartz Extreme (QE) on G3s or G4s that do not have a QE compatible AGP 2x graphics card. The hack is described here. From some tests that users did, it seems that only the G3/G4 machines with 66 MHz PCI bus saw some acceleration. Machines with 33 Mhz PCI bus, did not. The hack would work only if you have a Radeon or a GeForce2MX+ card, because they share the same driver with their AGP versions (QE only works on Radeons and GeForce2+ -- ATi Rage cards do not work at all with QE, with or without hacks). Also, please note that users who enabled QE on their unsupported PCI machines, had major artifacts on some applications, most notably iTunes' visual playback (quite possibly because the PCI bus is not fast enough for what is required).
