摘要
本文利用三维有限元网格图形的性质和计算数据结构的特点,提出了一种高效的空间立体网格图的消隐方法。该方法以最短的时间确定内部、外部单元面和快速生成不重复单元棱线,从而大大地提高了消隐效率。
This paper presents a new efficient hidden-line algorithm for the pre-or-post processes of FEM based on the graphic characteristics of finite element meshes and natures of the digital structure adopted in FEM. This algorithm is introduced to search internal or external element surfaces rapidly, and to produce unrepeated line and ploygons of element. This algorithm has made the hidden-line removing efficiently.
