1. A method of animating a digital facial model, the method comprising: defining a plurality of action units; calibrating each action unit of said plurality of action units via an actor's performance, wherein said each action unit includes a second facial pose data and an activation, wherein said activation of said each action unit is directed to a fascia layer, and wherein said calibrating each action unit includes calibrating said second facial pose data of said each action unit using calibration pose data derived from a calibration performance corresponding with said each action unit; capturing first facial pose data; determining a plurality of weights, each weight of said plurality of weights uniquely corresponding to said each action unit, said plurality, of weights characterizing a weighted combination of said plurality of action units, said weighted combination approximating said first facial pose data; generating a weighted activation by combining the results of applying said each weight to said each action unit; applying said weighted activation to said digital facial model; recalibrating at least one action unit of said plurality of action units using input user adjustments to said weighted activation; and cleaning and stabilizing said first facial pose data.
