Ray tracing engine for Quake III Arena produced
Slashdot Games has the scoop on an interesting project that's produced a real-time 3D ray tracing engine compatible with Quake III Arena. The engine offers some interesting visuals, including a plethora of real-time shadows and some very nice glass effects. Unfortunately, it takes a cluster with the equivalent of 36GHz of processing power to generate 20 frames per second at 512x512 with 4X FSAA.
The screenshots don't really do this engine justice, folks. Be sure to check out the video of Quake III: Raytraced in action to see all the neat effects in motion.
