Both Sharky Extreme and GameSpot have posted details on 3dfx' new technology, which will be used in their next chipset (currently called Napalm, or the Voodoo 4). The new technologies include full screen anti-aliasing, their proprietary T-Buffer, depth of field, and motion blur, and boths sites have good explanations of them for the lay folk out there. In addition to their article on the new technology, SE has also posted an interview with 3dfx' Scott Sellers, talking about their T-Buffer technology.
