摘　　要：围绕虚拟针灸仿真中在针灸力作用下皮肤变形效果的各种实现技术进行深入探讨;并结合虚拟人体经络系统中三维人体模型的实际结构的特征,对皮肤三维模型及皮肤受力模型的进行分析,最终在传统表面弹簧模型模型中引入虚拟力弹簧来表现皮肤表面模型的体特征。实验表明该方法即能满足针灸力作用下皮肤效果实时绘制的要求,又能体现皮肤受力作用产生变形的物理意义。All kinds of techniques for realizing the skin deformation under the force of acupuncture in the virtual acupuncture simulation were deeply discussed, and based on the feature and structure of 3D human model in virtual human jingluo system, the model of stress was analyzed. Finally, virtual force spring into mass-spring model was brought to represent the skin surface reformation. The result of test illuminates that this method not only can meet the requirement of real-time rendering for skin surface reformation, but also can represent its nhvsical nrineinle
