US Patent 9741146 Kinetic energy smoother

Embodiments disclose an animation system designed to generate animation that appears realistic to a user without using a physics engine. The animation system can use a measure of kinetic energy and reference information to determine whether the animation appears realistic or satisfies the laws of physics. Based, at least in part, on the kinetic energy, the animation system can determine whether to adjust a sampling rate of animation data to reflect more realistic motion compared to a default sampling rate.
