Computer-generated imagery (CGI) has become such a staple of modern movie-making that most people know what actors are doing when prancing around in front of green screens wearing skin-tight leotards with reflective balls affixed at various locations over their bodies - motion capture. In addition to the actor’s performance, such techniques can also require the tracking of camera movements and props so that perspective is maintained when translating the movements into CGI. Now researchers have demonstrated a system that can perform motion capture almost anywhere and without the need to track a separate camera and it does this by mounting the cameras on the actors instead.
