1. A motion-capture system, comprising: a host computing system; and a plurality of motion-capture cameras operatively coupled with the host computing system, where each of the motion-capture cameras is disposed in a different location and orientation relative to a motion-capture space and includes a marker-tracking optical filter that is wavelength selective to provide a marker-tracking mode and thereby relatively enhance light from markers on a moving body in the motion-capture space, where one or more of the motion-capture cameras is remotely controllable by the host computing system to actuate an automatic switching mechanism to selectively interchange the marker-tracking optical filter with a scene-view optical component, so as to selectively transition the motion-capture camera between the marker-tracking mode and a scene mode, in which light from the markers is less enhanced than in the marker-tracking mode, and where the host computing system is configured to calibrate the motion-capture cameras, where such calibration entails (i) using motion-capture cameras in the marker-tracking mode to detect markers within the motion-capture space; and (ii) processing, at the host computing system, information based on the detecting of the markers to determine the position of each of the motion-capture cameras relative to one another and relative to coordinates of the motion-capture space.
