PATH TRACING USED FOR REAL TIME MOTION CAPTURE
An Engadget article recently featured this video, showing a motion capture studio with live actors rendering in near real time via path tracing as robotic characters on a computer screen. The hardware setup they had uses three NVIDIA workstation graphics cards (a process that could be made virtually identically with much cheaper NVIDIA Titan cards) and the rendering quality is typical of path tracing - grainy in motion but resolves very quickly when paused. The path tracing software they used is from Vray, so, similar to VrayRT’s quality, their motion path tracing has black pixel defects (compared to other path tracers, like Arauna 2 or Brigade 3, where the motion quality is much better).
This represents a very real application of path tracing and can easily be applied to a motion capture studio that simulates walking through a digital version of an architecture project, especially if combined with a virtual reality headset like the Oculus Rift or Project Morpheus.
