Abstract:
Increasing physical accuracy has been a trend in many areas within the field of computer graphics. In this paper we discuss our approach to a problem that arises in the design of physically realistic animations that feature autonomous characters modeled as articulated figures. The problem is to specify a character’s trajectory (i.e., to compute the timedependent coordinates of each figure’s parts) so that the resulting motion is physically correct and conforms to the animator’s goals for the character (Badler et al., 1991).
