Abstract: A system includes a computing device that includes a memory configured to store instructions. The computing device also includes a processor configured to execute the instructions to perform a method that includes producing an animation model from one or more representations of an object provided from a deformable likeness of the object. The one or more representations are based upon position information from a collection of images of the object captured by at least one camera. The method also includes refining the animation model to produce representations that substantially match the one or more representations provided by the deformable likeness of the object. Refining the animation model is based upon the position information from the collection of images of the object and one or more constraints.
