摘要： 较好地解决了动画角色多运动规律模型随时连续切换难题，提出了一套人工鱼的局部运动规律建模与模型的随时连续切换方法。基于该方法开发了一个人工鱼社会行为系统，该系统能表现鱼的多种生命习性和智能行为。它能无限广义循环运行，有良好的人机交互性能。而且系统中鱼的外观、运动和行为在视觉上令人信服、逼真，不会出现动画角色“突变”、“突失”、“跳变”不佳视觉效果。提出的局部运动规律建模与模型的随时连续切换的思想方法对开发高效的、无限广义运行的、交互式的人工动物行为系统、动画系统有良好的借鉴作用。

Abstract: How momentarily continuously to switch the motion models of animated agents in animation is better settled. A way to establish local motion models of artificial fishes and a method momentarily continuously to switch the models are given. A society behaviour system of artificial fishes based on the way and method is exploited, which can exhibit life behaviours and intelligence of fishes. It can illimitably generalizedly circularly run and has good man-computer interaction. Moreover the appearance, motion and behaviour of the fishes in the system are lifelike and convinced. There are not bad visions such as ‘mutation’, ‘suddenly disappearing’, ‘jumpiness’ of animated agents. The proposed way and method are very useful for exploiting effective, interactive behaviour system of artificial animals and system of animation which can illimitably generalizedly and circularly run.
