| 摘 要： | 本文针对计算机绘图中截面交线法这种图形处理方法,在分析计算及消隐理论的基础上提出改进措施,使之不仅具有运算速度快、占用内存少的特点,而且克服了计算机绘图中常见的消隐不彻底的问题,较好地反映了三维立体曲面的图形。并且从不同方位进行动态观察曲面形体的尝试成为可能。

| Abstract: | in this paper,a cross—section line method of pictorial information pro- cessing in computer graphics is discussed systematically,and an improved algo- rithm based on the theory of computing and hiding is presented.This algo- rithm has features of faster computing and lower memory needed than other methed overcoming the defect of unperfect hiding,making the 3—D free— form surfaces well represented,which makes it possible to view surfaces changeably at different viewpoints. |
