Capturing and processing facial motion data includes: coupling a plurality
of sensors to target points on a facial surface of an actor; capturing
frame by frame images of the plurality of sensors disposed on the facial
surface of the actor using at least one motion capture camera disposed on
a head-mounted system; performing, in the head-mounted system, a tracking
function on the frame by frame images of the plurality of sensors to
accurately map the plurality of sensors for each frame; and generating,
in the head-mounted system, a modeled surface representing the facial
surface of the actor.
