虚拟人实时运动控制的研究

为在虚拟环境中再现逼真的人体运动，对虚拟人的实时运动控制进行了研究。简单阐述了对虚拟人体的几何建模和运动建模。在传统人体动画控制技术的基础上，提出了虚拟人行为的高、低两层控制策略，实现了虚拟人行为的智能化－－在低层运动控制部分，通过关键帧，正向、逆向运动学和简单动力学适当结合的多重控制技术对人体的关节直接控制，实现了周期地步行、跑步等移动动作；在高层运动控制中，研究了避免碰撞障碍物的路径规划和接近

Research of Real-time Motion Control for Virtual Human

In this paper, in order to demonstrate the real human motion in the VR environment we make a study of real-time motion control for virtual human. First. geometry modeling and motion modeling methods of virtual human are simply demonstrated Then, a motion control strategy with low and high levels is presented based on traditional control technology for human animation so that that intelligent behavior of virtual human is realized. In the low-level motion control, multiple control technology, which combines the keyframe. forward kinematics inverse kinematics and simple dynamics methods, is used to control the human's joints directly, and the periodical walking and running are generated. In high-level control we study the collision-free path planning procedure and add step adjustemnt module.
