Art-directable expressive oscillation behavior for rigged characters
Résumé
We propose a method to enrich the animation of rigged characters with exaggerated oscillation behavior triggered by a sudden velocity change. Our approach is based on the extension of Velocity Skinning to space-time deformation, where the deformation is computed from a time-filtered version of the angular velocity of the skeleton. The time-filter is easy to parameterize by artists with respect to frequency, magnitude and attenuation while remaining fully compatible with standard rigged character.
