Human crowds are ubiquitous in the real world, making their
simulation a necessity for realistic interactive
environments. We present a real-time crowd model based on
continuum dynamics. In our model, a dynamic potential field
simultaneously integrates global navigation with moving
obstacles such as other people, efficiently solving for the
motion of large crowds without the need for explicit collision
avoidance. Simulations created with our system run at
interactive rates, demonstrate smooth flow under a variety of
conditions, and naturally exhibit emergent phenomena that have
been observed in real crowds.
