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

The use of different state-spaces under different circumstances enables, for example, different state-spaces to be used for different ranges of musical tempo. For example, when no music is detected, a first state-space for a model can be used, when a tempo less than a first threshold value is detected, a second state-space can be used, and when a tempo above the first threshold is detected, a third state-space can be used. This allows for additional synchronization of the pseudorandom animation to different circumstances, and to customize motions (e.g. “dance” moves or combinations of motions from a particular state space) to be customized to different audio data within a single implementation of a computer animation model being executed on a device.
