摘要
在图学中求相贯线在投影面上的投影是十分重要的问题之一。本文提出了相贯线投影的最普遍解析法,并解决了如何求相贯线投影的极端点问题。
It is one of the important problems in the domain of graphics to determine the projec- tions of intersection line of surfaces.This paper develops an extremely general analysis for the projections of infersection line of surfaces and solves the problem of determing the ex- treme point of the projection of intersection line.
