NVIDIA Showing Fully Interactive GPU-Based Ray Tracer

NVIDIA is demonstrating what it says is the world’s first fully interactive graphics processing unit-based ray tracer this week at SIGGRAPH 2008 in Los Angeles. Based 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 fps at HD resolutions of 1920 by 1080 for an image-based lighting paint shader, ray traced shadows, and reflections and refractions. The demonstration is running on four next-generation Quadro GPUs in an NVIDIA Quadro Plex 2100 D4 Visual Computing System (VCS).
