• Dynamic Response for Motion Capture Animation

responses in unexpected situations e.g.,
reactions to impacts
time-varying physics-based

• How to compute a dynamic reaction
• to an unexpected impact based on
• motion capture data

Basic Idea
?
physics-based
data-driven
transition motions
transition-to motions
passive active

• a torque controller toward
• the chosen reaction
• a PD-servo

• a chosen from motion library
• consisting of reactive motions
• a reference for the active transition
• toward the (chosen) reaction
• the reaction itself

• solely driven by an impact
• a handle to choose a reaction
• from the library
• by deliberate delay
