摘　　要：文中应用面向对象的设计方法 ,针对消除隐藏线算法 ,为由点、直线段、多边形构成的立体图形设计了一种实体模型 ,该实体模型具有封装性和可维护性等面向对象设计方法的优点。同时由于记录了大量的立体图形的点、边、面的拓扑关系 ,使消除隐藏线算法减少了很多已知点、边、面查找相关的点、边、面的运算 ,从而提高了算法的效率 ,使在显示进行平移、放缩、旋转等变换的立体图形时 ,可较好地满足消除隐藏线的实时性的要求。In this paper, based on object-oriented design, we design an efficient solid model for 3-dimension object constructed by point, straight line and polygon to accomplish hidden-line detection method. It owns some advantage of object-oriented design, such as encapsulation and maintenance. Since it records many topological relation of points, edges, facets of solid object, it reduces many operation times in finding related points, edges, facets of given points, edges, facets. So that it enhances the efficiency of the hidden-line detection method and satisfies the real time demand.
