三维虚拟飞行角色的路径规划和姿态控制

摘要

According to the motion characteristics of flying characters in during the automatic generation of computer animation, a method for simplified scene modeling with octree is proposed. The reasonable and collision-free path can be planned in short time with improved heuristic function. The optimization with interpolation of control points is advanced to smoothen the path. What is more, the flying characters' pose can be well controlled with the method of attitude adjustment. The Experiments show that the methods can plan a more reasonable path. The results have certain optimality on the basis of the characteristics of flying characters. The satisfying effect of animation can be obtained. Therefore, the methods present certain application value.%针对智能动画生成过程中三维虚拟飞行角色的运动特点,设计了一种以八叉树进行简化场景建模的方法,通过改进启发式函数的设计,较快地为飞行角色规划出比较合理的无碰撞的路径,对规划出的路径使用控制点插值的路径优化策略进行平滑处理,在整个运动过程中支持姿态调整.试验表明该方法不但能规划出合理的飞行路径,而且在满足角色飞行特点的基础上具有一定的最优性,并且能获得较逼真的动画效果,具有较好的应用价值.
