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.

Embodiments of the present disclosure relate generally to computer animation and graphical user interfaces (GUI), including the generation and use of animation structures within a messaging system with access to audio data.
Computer animation involves adding movement to structures within a computer model that are output on a display of a device. Augmented reality is the display of the physical world and/or physical objects therein with an overlay of computer-generated perceptual information (e.g. animated computer models). The overlaid information may be constructive (adding to the display) and/or destructive (masking of the display). In either case, the computer-generated perceptual information can be animated to modify the information presented on a display of a device.
To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced.
