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(shuō)明書(shū)

Systems, methods, user interfaces, instructions stored in media, computing devices, and other various embodiments associated with configuring and generating animations are described. Certain embodiments particularly include structures for identifying a state-space of possible animations for a certain model. The state-space for a model can be described by possible motions of independent control points within the model, as well as animation speeds for each action and each control point. Each element of the state-space can have a probability assigned to configure pseudorandom animations with the probabilities of certain motions being configurable. Additionally, some embodiments include matching aspects of the pseudorandom animations to audio signals, as well as audio thresholds for initiating animations, and systems for matching the pseudorandom motions of a computer model to characteristics of an audio signal.
