Raytracing is Now Interactive on the GPU

Nvidia Another industry first is in the works this week during SIGGRAPH 2008 in Los Angeles--Nvidia is demonstrating the world's first fully interactive GPU-based ray tracer. Based purely on Nvidia GPU technology, the ray tracer shows linear scaling rendering of a highly complex, two-million polygon, anti-aliased automotive styling application. At three bounces, performance is demonstrated at up to 30 frames per second (fps) at HD resolutions of 1920x1080 for an image-based lighting paint shader, raytraced shadows, and reflections and refractions. The technology can be seen in the Nvidia booth, number 554, during SIGGRAPH.
