Abstract
The use of physically-based techniques for computer animation can result in realistic object motion. The price paid for physically-based motion synthesis lies in increased computation and information re-quirements. We introduce a new approach to realistic motion spec-ification based on state-space controllers. A user specifies a motion by defining a goal in terms of a set of destination states. A state-space controller is then constructed, which provides an optimal-control solution that guides the object from an arbitrary starting con-figuration to a goal. Motions are optimized with respect to time and control energy. Because controllers are specified in terms of desti-nation states only, it is easy to reuse the same controller to produce different motions (from different starting states), or to create a com-plex sequence of motions by concatenating several controllers. An implementation of state-space controllers is presented, in which re-alistic motions can be produced in real time. Several examples will be considered.
