| Abstract: | 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. |
