用全剖视图帮助重建三维实体算法的探索

AN INVESTIGATION FOR THE RECONSTRUCTION OF 3D SOLIDS BY MEANS OF CUTAWAY VIEW

本文提出一种算法 ,先把含有全剖视图的视图转化成相应子实体的视图 ,由此构造出三维子实体 ,再把三维子实体合并 .提供了一种利用全剖视图帮助重建三维实体的途径 .并在 Auto CAD平台上验证了算法的有效性 .本算法主要适用于剖切平面在实体对称位置的全剖视图 。

An algorithm, which can automatically construct 3D objects by m eans of some categories of 2D orthographic cutaway views, is proposed. First, the in putted drawing is transformed into views of some sub domains of the 3D object, i n such a way that all sub domains can be reconstructed. Summing up all the sub d omains gives the final 3D object. A reconstruction code according to the algorit hm was written in AUTOLISP and runs well on the AutoCAD platform.
