摘要
对被建模对象规划行为固有的不确定性建模可以让虚拟角色表现出不确定性行为,有助于提高虚拟角色的逼真度和可信度。以往的行为建模很少考虑虚拟角色的不确定性规划。对虚拟角色的不确定性规划建模进行了探索性研究。在不确定性函数的基础上给出了虚拟角色不确定性规划的概念。针对静态和动态不确定性规划分别给出了相关的建模方法。指出了不确定性规划建模存在的抖动问题,并设计了基于抖动阈值和备选计划集大小的防抖动方法。最后以虚拟坦克行为仿真验证了方法的可行性和有效性。
Modeling uncertain plan of virtual characters could make them behave in a non-deterministic way,which helped to improve the fidelity and credibility of virtual environment.In existing behavioral modeling,the uncertain behaviors of virtual characters were seldom considered.It was tried to model the uncertain plan of virtual characters in virtual environment.The concept uncertain plan was given based on uncertain function.The jitter problem of uncertain plan was raised,and the method that was against it was suggested based on jitter threshold.At last,through a virtual tank behavior simulation,the related work was validated.
