Nvidia: Hollywood can’t compete
by Ishida
According to some people at Nvidia, it may be too much for Hollywood to actually do real-time ray tracing. So far Cars, by Walt Disney, was the only movie that was able to use Ray tracing capabilities in full. Mental ray is one of the best ways of doing ray tracing and Nvidia owns it, but at this point no one from Hollywood even considers this as a real alternative.
They can still get away with the traditional ways of rasterization and light approximation. Photons and Ray casting and something for the distant future.
So this means games that utilize this technology will still be a little ways off as you can see the guy in the video above had to hook up 3 PS3s to do the real time rendering. Take note that the video has nothing to do with Nvidia as I just needed to pull off a video that roughly gives you an idea as to what Ray Tracing is.
