Crowd simulation is the process of simulating the movement of a large number of entities or characters, now often appearing in 3D computer graphics for film. While simulating these crowds, observed human behavior interaction is taken into account, to replicate the collective behavior.
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.
Animators typically create a library of motions, either for the entire character or for individual body parts. To simplify processing, these animations are sometimes baked as morphs. Alternatively, the motions can be generated procedurally - i.e. choreographed automatically by software.
The actual movement and interactions of the crowd is typically done in one of two ways:

Famous quotes containing the words crowd and/or simulation:
“Most literature on the culture of adolescence focuses on peer pressure as a negative force. Warnings about the wrong crowd read like tornado alerts in parent manuals. . . . It is a relative term that means different things in different places. In Fort Wayne, for example, the wrong crowd meant hanging out with liberal Democrats. In Connecticut, it meant kids who werent planning to get a Ph.D. from Yale.”
—Mary Kay Blakely (20th century)
“Life, as the most ancient of all metaphors insists, is a journey; and the travel book, in its deceptive simulation of the journeys fits and starts, rehearses lifes own fragmentation. More even than the novel, it embraces the contingency of things.”
—Jonathan Raban (b. 1942)
