We knew virtual camera systems are starting gain traction, particularly in the world of cinema and within James Cameron's little set of toys, but it's pretty wild to see one in action. NaturalPoint is showing off its OptiTrack motion capture system at GDC, a budget-friendly multi-camera setup (if $6k is your idea of budget-friendly), but it also has a prototype of sorts of its upcoming virtual camera system. The camera's orientation and movement is actually tracked in the same way a motion capture suit is, and if you're in the same tracking space as a motion capture actor you can do "real" camera work with a live 3D rendered preview of the action. The shoulder-mounted camera has controls for virtual tracking and dolly moves, along with zoom, and has zero problem delivering that shaky handheld look that's all the rage in visual effects these days. There's no word on much this will retail for, but despite the fact that we have absolutely zero use for it we totally want one. Check out a video of it in action after the break.
