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, ray traced shadows, and reflections and refractions running on four next-generation Quadro GPUs in an NVIDIA Quadro Plex 2100 D4 Visual Computing System (VCS). The technology demonstration can be seen in the NVIDIA booth 554 during SIGGRAPH.
