NVIDIA launches GPU based ray tracing at Siggraph

NVIDIA has announced that it can calculate ray traced imagery on the fly using its GPUs, claiming an industry first. 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.” if you want to get down and dirty, then the image shown here was displayed at three bounces, performance was demonstrated at up to 30 frames per second (fps) at HD resolutions of 1920×1080 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).

Now, I know ray tracing is incredibly complex and calc heavy, but, really, if this is an industry first, shouldn’t these images look better? I guess my point is that whether its full ray tracing, or fudged (some systems, like Autodesk Showcase, have some tricks to get over the calc hurdle), I think today’s users expect more in terms of depth of realism.
