Automated dance animation

說明書
Once a designer has finalized the configurable options for a computer animation model, the data for the finalized model can be made available through a messaging server system 108 or a messaging client application 104. In some embodiments, a user of a messaging client application 104 can access the model data, and include the model data in a message sent to another client device via messaging server system 108. When the receiving client device 102 plays the message, the model is implemented on the receiving client device 102 via messaging client application 104 to generate a video display. If no audio is detected, or if a threshold audio characteristic is not present, the receiving device 102 can simply display the skin or other aspect of the computer animation model in a display with a default animation or with no animation. If audio data is present, the receiving client device analyzes the audio data for audio characteristics such as a tempo value, and then uses the tempo value with motion states of the computer animation model to begin a video animation. An initial motion state is selected randomly from the possible motion states based on the probabilities for each motion state within the data received at the receiving client device. As long as the audio data is present and the receiving client device 102 is configured to continue the video animation, the computer animation model data will transition randomly between the motion states of the state-space for the model. The animation will end when the audio data ends or when the output animation is halted by a user input. In other embodiments, other options can halt an animation, such as an animation time, an ephemeral timer for a message that includes the data for the pseudorandom animation, or other such options. If the animation is part of an ephemeral message, after the message is presented with the pseudorandom animation and a deletion trigger is met, the model data is deleted from the receiving client device 102, so that additional animations using the particular computer animation model are not possible unless the model is retrieved independently or otherwise made available outside of the ephemeral message.
