      Crowds by example 

      Lerner, A.; Chrysanthou, Yiorgos L.; Lischinski, D. (2007)
      We present an example-based crowd simulation technique. Most crowd simulation techniques assume that the behavior exhibited by each person in the crowd can be defined by a restricted set of rules. This assumption limits ...
