| 摘 要： | 本文在总结边界表示法（ＢＲ）的结构式立体几何表示法（ＣＳＧＲ）重建三维图形的基础上，提出了一种基于两者结合的三维重建方法。采用ＢＲ方法，把工程图纸的二维矢量化信息作为原始数据，逐步恢复三维点，三维边，面及ＣＳＧＲ意义下的基元体。采用ＣＳＧＲ方法，组合基元体，最终生成复合体，重建三维图形。算法以多面体为研究对象，在ＷＩＮＤＯＷ５３．０环境下实现。

| Abstract: | Both the BR(Boundary Representation) algorithm and the CSGR (Constructive Solid Geometry Representation) algorithm of reconstructing 3D solid objects are summed up in this paper, and the algorithm based on the combination of both is proposed. When 2D vector information from three engineering drawings is used as input, 3D vertices, 3D line segments and faces and 3D subjects are recovered step by step by means of BR CSGR is utilized to combine the probable 3D subobjects and reconstruct 3D solid objects finally. Polyhedrons are studied and the algorithm is implemented under WINDOWS 3.0. |
