Abstract:

The first step in creating a computer animation is often the definition of a time varying geometric model. Realistic movement sequences can be obtained through physically-based simulation and optimization programs. This paper presents a method for representing movement sequences as streams and describes a system for editing motion streams. The approach allows motion streams to be filtered, duplicated, transformed, and combined. Cameras with prescribed motions can be introduced to visualize scenes. A general facility for composing sequences of spatial transforms permits the specification of complex trajectories and relative motion. Motion stream editing facilitates the synthesis of intricate movement sequences that can be rendered as animation or presented as the input circumstances for additional simulation.
