Abstract
A method, comprising: generating facial muscle activations from facial marker data; animating a computer graphics facial model using the facial muscle activations; generating a skin layer overlaying the computer graphics facial model; and animating the skin layer using the facial marker data.
Claims23
A method, implemented in a computer system, comprising:
- generating facial muscle activations from facial marker data by determining weights that characterize a weighted combination of action units approximating the facial marker data,
- wherein each action unit of the action units defines a predetermined facial muscle activation that produces a change in facial appearance;
- animating, the computer system, a computer graphics facial model using the facial muscle activations;
- generating a skin layer overlaying the computer graphics facial model;
- and
- animating the skin layer using the facial marker data.
3 more elements
A system, comprising:
- a facial muscle activations module to receive facial marker data and to generate facial muscle group activations by determining weights that characterize a weighted combination of action units approximating the facial marker data,
- wherein each action unit of the action units defines a predetermined facial muscle activation that produces a change in facial appearance;
- an animation module to receive the facial muscle group activations and generates an activated facial model;
- and
- a skin layer module to receive the activated facial model and the facial marker data, and to generate an animated skin-layered facial model.
