Human motion capture embeds rich detail and style
which is diffcult to generate with competing animation synthesis
technologies. However, such recorded data requires principled
means for creating responses in unpredicted situations, for
example those immediately following impact. This paper introduces
a novel technique for incorporating unexpected impacts into
a motion capture-driven animation system through the combination
of a physical simulation which responds to contact forces and a
specialized search routine which determines the best plausible reentry
into motion library playback following the impact. Our system
generates a physics-based response as it transitions between
motion capture segments using an actuated dynamic model and
smoothly moves the character toward the re-entry clip over time.
Our method allows characters to have un-canned responses to unexpected
changes in the environment based on the specific dynamic
effects of a given contact while also taking advantage of the realistic
movement made available through motion capture. We show
the results of our system under various conditions and with varying
responses using martial arts motion capture as a testbed.
