辐射屏蔽组合体的可视化研究

Visual Research for Radioactive Shield Assembly

为了解辐射屏蔽组合体的结构和分布,对其作了可视化仿真研究。首先建立了多个基本几何形状的数学模型来完成组合体的绘制。空间坐标变换法的使用可大幅度简化绘制过程。然后用混合法绘制不透明物体和半透明物体。使用混合的方法可使组合体中的内部结构都能显示。组合体的着色和光照可通过菜单、对话框来变更。组合体的移动和旋转可由键盘和鼠标的操作来控制。该文中显示了一个由管道、圆柱体和箱形体所组合成的屏蔽组合体的绘制结果。

In order to understand the construction and distribution of the radioactive shield assembly,the visual simulation has been studied.At first,some mathematic models of the basic geometry have been built to realize the rendering of the radioactive shield assembly.The rendering of assembly can be simplified greatly by space alternate coordinate.Then a blend method has been developed for rendering the opaque body and translucent body.Using blend method,the interior construction of the assembly can be displayed.The coloring and lighting of the assembly can be modified with the menu and dialogic frame.The move and revolution of the assembly can be controlled through the operation of the keyboard and wheel mouse.As an example,the assembly made up of pipe,circular cylinder and box is shown in this paper.
