Crowd simulation

Crowd simulation is the process of simulating the movement of a large number of entities or characters; this technique is now commonly used in 3D computer graphics for film. While simulating crowds, observed human behavior and interactions are taken into account to replicate collective behavior. It is a method of creating virtual cinematography.

The need for crowd simulation arises when a scene calls for more characters than can be practically animated using conventional systems, such as skeletons/bones. Simulating crowds offer the advantages of being cost effective as well as allow for total control of each simulated character or agent.
