摘要
利用透视投影理论，对立体模型表面可视性、排序、多边形填充等算法作了数学分析．通过对立体模型的数据建立、表面可视性计算、立体模型到平面的映射、多边形填充等步骤，实现了立体模型的计算机显示．结合这一理论，用Ｃ语言编制程序，实现了三维建筑图的计算机模拟显示．
y using the theory of perspective projection,the mathematics analysis of many algorithms such as visible surface,sequencing,polygonal filling are explained.Through data establishment of 3D model,computing of surface visiblity and the mapping of 3D model to plane,the computer display of 3D model is realized.Combined with the theory and C computer language, a colorful real and beautiful building is successfully displayed on computer screen.The theory guide is offered for a 3D models being expressed on plane,the change is realize from the theory to practice.
