Group Motion Graphs
Proceedings of the ACM SIGGRAPH Symposium on Computer Animation — jul 2005
We introduce Group Motion Graphs, a data-driven animation technique for groups of discrete agents, such as
flocks, herds, or small crowds. Group Motion Graphs are conceptually similar to motion graphs constructed from
motion-capture data, but have some important differences: we assume simulated motion; transition nodes are
found by clustering group configurations from the input simulations; and clips to join transitions are explicitly
constructed via constrained simulation. Graphs built this way offer known bounds on the trajectories that they
generate, making it easier to search for particular output motions. The resulting animations show realistic motion
at significantly reduced computational cost compared to simulation, and improved control.
