1 CS 326 A: Motion Planning http://robotics.stanford.edu/~latombe/cs326/2004 Motion of Crowds and Flocks

2 Origin: Boids http://www.red3d.com/cwr/boids / Potential fields alignement cohesion separation

5 Limitations of Potential Fields Lack of global control Many parameters to tune Local minima  Combination with motion planning methods

6 Applications Video games Background in movie generation, e.g.: - people on deck of Titanic, - battle scenes in Napoleon TV series Design of buildings, e.g.: - sport stadium - emergency escape routes

7 Papers –Use of PRM: O.B. Bayazit, J.M. Lien, N.M. Amato. Better Flocking Behaviors in Complex Environments using Global Roadmaps. –Follow-the-leader model: T.Y. Li, Y.J. Jeng, S. Chang. Simulating Virtual Human Crowds with a Leader-Follower Model.
