RIGGING METHOD FOR FACE MOVEMENT OF DIGIT CREATURE BY FACIAL CAPTURE APPLYING TO DIGITAL GAME IMAGE

PURPOSE: A method for expressing facial movements by capturing the face of a digital creature is provided to express realistic facial movements without shape distortion or errors. CONSTITUTION: A method for expressing facial movements by capturing the face of a digital creature comprises the following steps: attaching a marker to a human face and producing motion capture data by filming the movement of the marker using a photographing device; producing a motion capture layer which produces a motion capture locator which moves using transform data extracted from the motion capture data; producing a skull geometry and a skull layer which produces the skull locator moving on a skull geometry; producing a facial geometry corresponding to the facial surface of the digital creature and a deformation layer which corresponds to the motion capture locator and produces a joint located on the facial geometry surface; and deforming the facial geometry through the joint which operates by being linked with the skull locator moving on the skull geometry.
