We introduce Group Motion Graphs, a data-driven animation technique for groups of discrete agents, such as flocks, herds, or small crowds. Graphs are conceptually similar to motion graphs constructed from motion-capture data, but have some important differences: we assume simulated motion; transition nodes found by clustering group configurations the input simulations: and clips join transitions explicitly via constrained simulation. built this way offer known bounds on trajectories that they generate, making it easier search particular output motions. The resulting animations show realistic at significantly reduced computational cost compared simulation, improved control.
