Motion Control: from Keyframe to Task-level Animation

These techniques are important because they allow to visualize any geometrical, physical or chemical situation to be visualized at any given time. However, the most interesting aspect of many phenomena is their evolution over time; e.g. motion of electromechanical devices (robots), chemical reactions, fluid motion, cloud motions, heat conduction. Experiments are often very expensive and sometimes impossible; e.g. crashes, explosions. It is generally easier and less expensive to produce computer simulation of phenomena.
