Deformable Object Animation Using Reduced Optimal Control
Keyframe animation is a common technique to generate animations
of deformable characters and other soft bodies. With spline interpolation,
however, it can be difficult to achieve secondary motion
effects such as plausible dynamics when there are thousands of degrees
of freedom to animate. Physical methods can provide more
realism with less user effort, but it is challenging to apply them
to quickly create specific animations that closely follow prescribed
animator goals. We present a fast space-time optimization method
to author physically based deformable object simulations that conform
to animator-specified keyframes.
