摘要

Methods, devices, media, and other embodiments are described for generating, modifying, and outputting pseudorandom animations that can be synchronized to audio data. In one embodiment, a computer animation model made up of comprising one or more control points is accessed by one or more processors, which associate motion patterns with a first control point of the one or more control points, and associate one or more speed harmonics with the first control point. A set of motion states is identify with a motion state for the combinations of possibilities, and a probability value is assigned to each motion state of the set of motion states. The probability value can be used to probabilistically determine a particular motion state to be part of displayed animation for the computer animation model.

說明書

FIG. 7C illustrates aspects of motion patterns 780 that can be used as part of an animation state-space in accordance with some embodiments, and FIG. 7D illustrates aspects of a computer model that can be used as part of a system for generating and displaying animations in accordance with some embodiments. FIG. 7D illustrates a bone 760 having joints 750 and 770. In FIG. 7D, joint 750 is a reference point for bone 760, and joint 770 is a control point, with motion patterns for control point 770 defined in a spherical surface 774 around joint 770 having a maximum range of motion 772 illustrated as range 772A and 772B.
