"The quality of 3-D computer graphics is poised for a quantum jump forward, thanks to speedier ways to simulate the flight of light "
"Ray tracing is something of a holy grail in graphics processing. By using standard optics equations to calculate the paths that light takes in a scene, a 3D renderer can produce scenes that are much more realistic than those produced by the kind of raster graphics that powers all 3D games and most computer-animated movies."
"I think it's reasonable to guesstimate that a four-core Conroe or Athlon 64 system would get you to the point where you could do real-time ray tracing at 450M raysegs/s or higher. This would put software-based real-time ray tracing well in reach of a God Box in late 2007, and a Performance Gaming Box not too long thereafter. These numbers also make me wonder if you couldn't do real-time ray tracing on a PS3, or even on an Xbox 360 (less concurrency than the PS3, but higher per-thread performance). "
Man, I'm so psyched about this.
