| 摘要: |
| 利用组合体形体分析法对组合体几何造型方法进行了研究，采用边界表示法，以面、环、边、点层次结构来定义物体，并进行体素拼合运算和相应的图形显示处理。自行开发的软件系统实现了交互式基本体素的造型，通过拼合运算生成组合体，并根据造型产生的立体几何信息及拓扑信息进行图形变换。 |

| Abstract: |
| Based on the principle of construction analysis, the method of solid geometricmodeling is discussed. By using B-Reps, the object is recorded by a hierarchical datastructure of face, loop, edge and vertex. The object Boolean operations and graphicsdisplays are carried out. The software system can accomplish the interactive elementsmodeling, the Boolean operations and the graphics translations according to the geometricalmeasurments and topological information. |
