US Patent 9396574 Choreography of animated crowds

Techniques are proposed for animating a plurality of objects in a computer graphics environment. A crowd choreography system receives a first beat description defining potential motions for the plurality of objects, where the first beat description includes a first motion characteristic. The crowd choreography system selects a first object from the plurality of objects and selects a first value for the first motion characteristic based on the first beat description. The crowd choreography system creates a first motion path for the first object based on the first value and animates the first object based on the first motion path.
