Abstract:
This paper describes a technique that employs cost functions to
produce complex motions. Cost functions can be used to define
goal-oriented motions and actions. A cost function can be defined
whose variables are the animated parameters of a scene. The parameters
are modified in such a way to minimize the cost function. The minimum
cost configuration can be viewed as a "key goal" configuration. The
values of the parameters are stored at certain intervals during the
minimization process. This produces a path through the parameter space
of the model being animated. By incrementally moving along the
parameter space curve and updating the model defined by the
parameters, an animation of the model performing a goal-oriented
action may be produced.
