Diffusive Pathfinding

2016-11-22T02:12:06.392Z

Testing density-aware pathfinding within a potential field based crowd model. By using dynamic density values as weights within the calculation of geodesic distances, crowds are encouraged to explore alternative routes when direct ones become too congested. Based on approach presented by Treuille et al. in (1).
