Tom heeft een artikeltje gepost over de Siggraph 99 beurs, die afgelopen week in Los Angeles werd gehouden. Tom heeft nieuws over nieuwe technologiŽn van o.a. nVidia, 3dfx, 3DLabs en Number 9. Hier een stukje over de T-Buffer technologie van 3dfx (gaan ze dan toch eindelijk serieus sleutelen aan de beeldkwaliteit van de Voodoo?):
Peter Wicher, Director of Product Marketing, gave me a demonstration of 3dfx's T-Buffer technology at the company's meeting room in an off-site hotel. The demos were running on a Quantum 3D configuration of about 4 Voodoo 2 SLIs so, it was an emulation, but the results were pretty obvious. T-buffer does do a very admirable job of full-scene anti-aliasing, motion blur, depth of field blur, soft shadows, and soft reflections. It's pure visual quality.
While I can see how the anti-aliasing component will have an immediate impact, I am less sure of the motion blur, and depth of field blur effects. Once the effects are pointed out, the impact is significant, but both are going to require developers to think really hard about how they implement these techniques in a real-time interactive 3D environment. Take depth of field blur, or focal blur. Basically, this is when the camera will focus on a character or object in the foreground, and the background will be out of focus. In 3D scenes today, the depth of field is infinite, but 3dfx's T-buffer would allow developers to change the focus of the scene as if the camera was focusing on one particular aspect of the scene. It's really quite nice to watch, but it is a cinematic effect, and it will require a tremendous amount of skill to get right in a dynamic environment.
