摘　　要：分析了使用网格法参数化绘制已知曲面方程三维曲面图形的方法.该方法的优点是在绘制三维空间曲面时,可以方便地使用有关参数对三维空间曲面图形进行控制.这在很大程度上增强了计算机辅助设计系统的三维造型功能,对于不易直接用计算机辅助设计系统绘制但又已知曲面方程的三维空间曲面,都可以利用网格法准确、快速、方便地进行参数化造型.The method of drawing 3D camber figure of the given camber equation with the parameterization of the grid way is introduced. The advantage of the method is that relevant parameters can be easily used to control the 3D camber figure while drawing the 3D camber figure. The applicability of the method of the parameterization of the grid way is wide and intensifies greatly the function of drawing 3D camber figure by means of the supplementary designing system in some computers. When the supplementary designing system cannot be directly used in some computers to draw 3D camber figure with the given camber equation, the method is a better choice in the exactness, speed and convenience of drawing 3D camber figure.
