摘　　要：针对虚拟人皮肤表面参数表示方法中曲面形状难以控制、曲面间平滑连接不易实现的不足,研究了一种基于Bézier曲线的虚拟人皮肤表面变形方法;结合插入过渡段的人体分段方法和径向截面法实现了对Bézier曲线形状的有效控制,克服了传统参数表示方法中曲面难以平滑连接及皮肤表面细节难以描述的缺点,并实现了大臂肌肉和肘部皮肤随肘关节角度变化的实时变形。For it is difficult to control the surface＇s shape or to connect surfaces smoothly in the traditional spline surface modeling method of the virtual human skin,this paper studied a skin deformation method using Bézier curves.The shape of Bézier curves could be controlled effectively by inserting transition segments and using radial section method,and resolved the defaults of difficulties of connecting the continuous surfaces smoothly or describing the skin details.And it realized the arm muscle and elbow surfaces deformed with the elbow joint angle.
