1. A method of capturing and processing motion data of a facial surface of an actor, comprising: projecting speckle patterns on the facial surface of the actor using near-IR light to enable triangulation; capturing frame by frame images of the speckle pattern applied on the facial surface of the actor using at least one motion capture camera disposed on a head-mounted system by tracking and analyzing movement of the speckle pattern; performing, in the head-mounted system, a tracking function on said frame by frame images of said plurality of sensors to accurately map said plurality of sensors for each frame; and generating, in the head-mounted system, a modeled surface representing the facial surface of the actor by triangulating the speckle patterns.
