Abstract
An interactive application may include a quasi-physical simulator configured to determine the configuration of animated characters as they move within the application and are acted on by external forces. The simulator may work together with a parameterized animation module that synthesizes and provides reference poses for the animation from example motion clips that it has segmented and parameterized. The simulator may receive input defining a trajectory for an animated character and input representing one or more external forces acting on the character, and may perform a quasi-physical simulation to determine a pose for the character in the current animation frame in reaction to the external forces. The simulator may enforce a goal constraint that the animated character follows the trajectory, e.g., by adding a non-physical force to the simulation, the magnitude of which may be dependent on a torque objective that attempts to minimize the use of such non-physical forces.
