摘　　要：研究虚拟人体运动仿真动画技术是计算机动画设计中极重要的课题,构建简化虚拟的人体几何模型,利用计算机图形学知识,针对人体几何建模复杂,逼真度、控制性差的问题,先优化设计人体仿真运动相应的数学模型,建立人体运动系统坐标系后,采用Denavic—Hartenberg法,建立虚拟人体分层结构运动链的空间关节坐标系统。在3DS MAX下进行逼真几何建模,把模型转化为OpenGL程序,运用Visual C++6.0和OpenGL为编程工具,实现虚拟人体关节运动控制。结果表明,建模逼真,优化的几何模型在软件下容易控制,整体效果好,增强了虚拟人体运动的真实感和动作效果,很好地实现了虚拟人体行走。Human animation is one of the challenging tasks in the field of computer animation.To solve those sophisticated problems such as complex geometry model,simulation degree and hard to control,we must build a model to select best human motion simulation at first,then simplify the human model of geometry.We can present a space index of human motion with knowledge of computer graphics and methods of Denavic-Hartenberg,offer an articulation space index of simulation of human being.We take waist articulation as basic index,take every joint of articulation to present particular index,and construct a hierarchy joint chain of human motions.Finally,we construct a geometry model with 3DS MAX,then transform the model into OpenGL program by making use of tools such as Visual C＋＋6.0 and OpenGL to simulation of human walking.By practice,we achieved better visual model simulation,the human motion can be controlled easily,and the simulation walking of human is strengthened.
