FIG. 6A illustrates aspects of motion patterns 600 that can be used as part of an animation state-space in accordance with some embodiments. In FIG. 6A, six example motion patterns 610, 612.614, 616.618, and 620 are illustrated. Each motion pattern is shown in a movement space 602 for an example control point. For example, if motion pattern 618 is selected, the control point that motion pattern 618 is selected for will move in a circular pattern as shown. If motion pattern 616 is selected, the control point will move back and forth linearly in a single direction as shown. Motion patterns 610-618 are intended to show simple motion patterns along a fixed path. Other motion patterns with more complex characteristics are also possible. For example, with motion pattern 620, a particular path is not described, but motions are possible anywhere within the circular shape, but prohibited outside the circular shape in areas that are still possible within the constraints of the acceptable motions for the control point defined by movement space 602.
