摘要： 用空间坐标变换法将曲面辐射屏蔽体的数学模型简化成标准型。通过模型变换法,可用球体和圆柱体来代替椭圆球和椭圆柱。对于弯管和环面状几何对象,先在新坐标系上确定其一组组顶点,然后由这些顶点绘制其图形。图形在标准位置上被绘制后,通过坐标平移和旋转转换到给定位置上进行显示,从而可大幅度简化绘制过程。所绘制的图形能连续变化而且图形的着色和光照可通过菜单、对话框来变更。

Abstract: The method of space-alternate-coordinate is used to simplify the mathematic models of camber radioactive shield configurations intothe standard models. The transformation of model is the replacement of ellipsoid and elliptical cylinder for sphere and circular cylinder. For elbowand torus, their vertexes in a new coordinate system have been determined, and then the configuration can be drawn from these vertexes. Havingbeen shifted and revolved the coordinate, the configuration is shown at the designative place decided by known conditions. So the rendering ofconfiguration can be simplified greatly. The configurations can be revolved continuously and coloring and lighting of the configuration can bemodified with the menu and dialogic frame.
