鱼群动画的行为规划

Behavior Planning in Animation of Fish Shoal

针对鱼群动画中人工鱼的行为选择(策略、目标、规划)过程,基于认知建模方法,提出一种建立人工鱼认知角色模型的新方法.利用高层非确定性目标导向行为与低层确定性预定义行为相结合的协调控制方案,以目标优先级作为行为选择的依据来制定人工鱼的行为规划.仿真实验结果表明,此方法不仅使人工鱼能根据外部刺激和内部状态选择适当的行为,且能较好地体现出自然鱼的特征.

Focusing on the selection process of shoal behavior animation （strategy, goal and plan）, and using the cognitive modeling approach on behavior selection, a new method to build a cognitive model of artificial fish in fish shoal animation is presented. Using a concerted control scheme that combines the high-level uncertainty goal-directed behavior and lower-level predefined behavior, and with the warrant of behavior selection based on goal priority, the behavior planning is established. Simulations results show that this method can make artificial fish choose required behavior based on outside stimulate and inside state, and achieve quite natural characteristics of real fish.
