要创建深度沉浸的跑步竞赛虚拟环境,则必须建立逼真的虚拟人行为模型。根据跑步时人体四肢和躯干都在绕关节做重复旋转运动的特点,提出一种基于旋转角度的运动行为模型,用于计算人体运动时不同部位的位置,进而求解跑步运动行为。基于该模型开发了一个跑步仿真程序用来仿真虚拟人的跑步动作与姿态。根据该模型构建了数字娱乐划船器,通过三维模型数据的转化、运动者参数的实时采集、虚拟人运动参数的计算,实现了角色的控制。该建模与控制方法可用于网络健身游戏、虚拟人体动画、虚拟机器人的建模与仿真。
A move action model was put forward.Such model constructs posture functions and calculates locations of each part according to round angle of joints.Based on such model,a run animating simulation program was developed,which could be applied to simulate runner gesture.A digital entertainment boating was developed based on such model,which realized role control by three-dimensional model data conversion,real-time data acquisition,and by calculation of virtual human motion parameters.The modeling and control m...
