Abstract:
This paper describes algorithms for the animation of men and women
performing three dynamic athletic behaviors: running, bicycling, and
vaulting. We animate these behaviors using control algorithms that cause
a physically realistic model to perform the desired maneuver. For example,
control algorithms allow the simulated humans to maintain balance while
moving their arms, to run or bicycle at a variety of speeds, and to
perform a handspring vault. Algorithms for group behaviors allow a number
of simulated bicyclists to ride as a group while avoiding simple patterns
of obstacles. We add secondary motion to the animations with spring-mass
simulations of clothing driven by the rigid-body motion of the simulated
human. For each simulation, we comparethe computed motion to that of
humans performing similar maneuvers both qualitatively through the
comparison of real and simulated video images and quantitatively through
the comparison of simulated and biomechanical data.
