Scripting Interactive Physically-Based Motions with Relative Paths and Synchronization

摘要

This paper presents a novel approach for facilitating the use of physically based models by animators The idea is to let the user guide motion at a high level of control by giving approximate desired trajectories and synchronization constraints between the objects over time, while a simulation module computes the final motion, dealing with collision detection and response, and enhancing realism. The objects, which are either isolated or components of an articulated structure, are guided through the specification of key-positions and orientations, defined by coordinates that can be fixed or relative to another object.
