计算机绘制圆环透视图的新方法

A New Aegorithm of Perspective of the tours Drawn by computer

用计算机绘制圆环面的透视图和消除隐藏线,是一个较复杂的问题。本文提出一个建立在画法几何及初步几何原理基础上的处理方法,简称锥面逼近法。通过上机实践表明,本方法具有简便易行的优点。

It is somewhat difficult to draw the perspective of tours and eliminating its hidden line bycomputer.In this paper a new algorithm for solution above-mentioned problems is drived,based upon the pirinciple of the desriptive and elemential geometry,the algorithm is carried outa program,there are indications,that the algorithm was successful,according to the results ofoperation of the program.
