Crowd AI
The entities - also called agents - are given artificial intelligence, which guides the entities based on one or more functions, such as sight, hearing, basic emotion, energy level, aggressiveness level, etc. The entities are given goals and then interact with each other as members of a real crowd would. They are often programmed to respond to changes in environment, enabling them to climb hills, jump over holes, scale ladders, etc. This system is much more realistic than particle motion, but is very expensive to program and implement.
The most notable examples of AI simulation can be seen in New Line Cinema's The Lord of the Rings films, where AI armies of many thousands battle each other. The crowd simulation was done using Weta Digital's Massive software.

Famous quotes containing the word crowd:
“The wide wonder of Broadway is disconsolate in the daytime; but gaudily glorious at night, with a milling crowd filling sidewalk and roadway, silent, going up, going down, between upstanding banks of brilliant lights, each building braided and embossed with glowing, many-coloured bulbs of man-rayed luminance. A glowing valley of the shadow of life. The strolling crowd went slowly by through the kinematically divine thoroughfare of New York.”
—Sean O’Casey (1884–1964)
