摘要
提出了一种基于STL实体模型的新网格剖分方法,其主要思想是:首先沿Z轴方向进行分层剖分,每一个分层平面与模型相交会产生若干封闭的二维轮廓线区域,然后利用扫描线填充算法对二维轮廓线区域进行填充即可完成整个模型的网格剖分。在此基础上又进而开发了相应的网格自动剖分软件。
A new grid-generation method based on STL solid model has been put forward in this paper. The main principle is: first of all, using STL solid model's continuity to speed up the process of model's cutting, and the contour lines of each layer were calculated. Secondly, on the cutting planes, according to area filling algorithm, the cells enveloped by contour lines were determined and given an according material number. On this basis, a software was developed.
