New VR system aims to replace on-site filming

On a soundstage no bigger than a large bedroom a cameraman takes up various angles to film a helicopter that isn't there, landing on a field that isn't there either.

Until recently, virtual reality was the preserve of the gaming crowd but producers say the technology is on the cusp of a boom that could change forever the way television is done.

Leading the charge is visual effects studio CBS Digital, which has developed Parallax, a VR system that could potentially do away with on-location filming altogether.
