Via Arena has an editorial on whether the era of physics (or PhysX) has begun:
The advent of the 3D accelerator was nothing less than revolutionary. Yet this bold claim is the assertion of start up company AGEIA Technologies. John first met with AGEIA at E3 2004, when they were demonstrating in software mode. This year AGEIA are demonstrating retail solutions. They have successfully brought the world’s first physics processing unit (PPU) to market. John had another chance to sit down with Andy Hess, Director of Developer Marketing from AGEIA, at E3 2006. John provided me with the full Press Kit and an MP3 recording of that interview. He then conveniently hopped on a plane to Vegas for the annual “VIA Vegas” meeting of the VIA Arena forum moderators, leaving me to put together this article! (Half his luck!) All of the quotes in bold featured in this article were taken from John’s interview. The meeting put their technology into the perspective and gave good insight into the potential of the PPU.
