Abstract: A system includes a computing device that includes a memory configured to store instructions. The system also includes a processor configured to execute the instructions to perform a method that includes receiving multiple representations of one or more expressions of an object. Each of the representations includes position information attained from one or more images of the object. The method also includes producing an animation model from one or more groups of controls that respectively define each of the one or more expressions of the object as provided by the multiple representations. Each control of each group of controls has an adjustable value that defines the geometry of at least one shape of a portion of the respective expression of the object. Producing the animation model includes producing one or more corrective shapes if the animation model is incapable of accurately presenting the one or more expressions of the object as provided by the multiple representations.

Abstract: A computer-implemented method includes identifying a primary node that represents a first pose of an online character. The first pose is associated with a constraint being inactive. The method also includes identifying the primary node representing a second pose of the online character. The second pose is associated with the constraint being active. The method also includes calculating the difference between the primary node of the second pose and the primary node of the first pose. Further, the method includes applying the difference to the primary node of the first pose.
