Fish exhibit a wide variety of behavior, including swimming and schooling. Animating a school of fish is difficult because of the large number of fish and because a school of fish often swims in distinctive and coordinated patterns, particularly when they are attacked by a predator. Previous work in computer graphics has not provided satisfactory models to simulate the many distinctive interactions between a school of prey fish and their predator. In this paper, we present a fish school escape behavior model that can simulate 12 fish escape maneuvers identified in biological studies: compact, avoid, fast avoid, skitter, fountain, flash, ball, split, join, herd, vacuole, and hourglass. This behavior animation model can free an animator from dealing with the low‐level animations but instead controls the fish behavior on a higher level by modifying a state machine and a small set of system parameters.
