ABSTRACT:
A system and method for animating a character with activation-driven muscle deformation. External loads can be estimated through an iterative joint torque estimation process, and the external loads reflected in a physical model. Kinematic motion and the physical model reflecting external loads can be used to estimate joint torques. Muscle activations can be determined from the joint torques, and a character can be animated with muscle deformation responsive to the muscle activations.
