摘要
本文讨论三维实体有限元模型网格图的消隐问题。分析了它的数据结构、几何特征及图形表达等方面的特殊性,并对这类图形的计算机绘制计算方法作了初步探讨,提出了一些实用算法,并给出实例。
The paper concerns with the elimination of hidden lines/surfaces emerged in mesh diagrams for 3-D finite element models. Specific features regarding data structures, geometric characteristics, as well as graphical representations of such models are discussed. Efforts are made in search of a method for generating mesh diag- rams capable of exhibiting no hidden lines nor hidden surfaces by use of computer graphic system. Thence, a sort of practical algorithm is developed, with examples indicating the effectiveness and simplicity of the algorithm.
