摘　　要：提出一种新的虚拟手建模和“分而治之”的运动控制方法。根据人手结构与运动特性,把人手形象化球棒状,本文利用NeoAxis搭建3D场景及虚拟手模型,降低代码编写成本,提高效率,可简易快速实现人手的几何模型的创建,使本来复杂的手结构简单化,更有利于人手结构形态的分析,以便能更形象逼真的实现人手的运动跟踪,并能实现虚拟对象的抓取。最后通过实验进行了较好的验证,建模方法简单易实现且能满足各种实时应用的需求。Hand natural motion,especially virtual object grasping,is difficult to animate because the hand has not only the high number of degrees of freedom b ut also the need to conform naturally to the object surface.This paper proposes a new approach for modeling the human hand that has natural motion.The human h and is a complex articulated structure.Each finger translates or rotates around its palm,which is determined by joint rotation.According to the anatomical st ructure and the human hand motion characteristics,we establish a virtual ball-a nd-stick geometric model.This hand model can well simulate the movement of the hand is designed.It can analyze the joint characteristics of the hand and the r elationship between the joints.The"divide and conquer"strategy is used to con trol the movement of the opponent model through the principle of kinematics.Neo Axis is used to build 3D scenes simulating realistically hand natural motion whi ch can reduce the cost of coding and improve efficiency.Simplification is more conducive to the analysis of the structure of the human hand,so that the moveme nt of the human hand can be more vividly tracked,and the virtual object can be grasped.Finally,a good verification is made through experiments.The modeling method is simple and easy to implement and can meet the needs of various real-t ime applications.
