NVIDIA to power cloud-based raytracing

The company hosts 32 Fermi processors in a cloud-based server that are simultaneously working on the same image. Rendering simulations can be done remotely in realtime, whereas in the past they had to be pre-rendered by massive supercomputer clusters. “Simulating reality is a very computationally intense problem, and the only solution to it in the past was to figure out ways to simplify the process to maximize the simulation realism,” said [Autodesk's Ken] Pimentel. “Here, we are physically simulating every photon as it passes through the scene. We aren’t interpolating.”
