摘要
直线与曲面相交求交点的问题,可以根据直线与曲面之间的相互位置关系以及它们相对投影面的位置关系和曲面特性,采用辅助平面法、辅助射影法和反演变换法改变直线和曲面的投影特性后求解。
The problem of intersection point of a straight line with a curved surface can be solved on the basis of the interrelation of their positions, their opposite projection and surface characteristics, by changing their projection characteristics through the methods of supplementary surface, supplementary projection and inverse evolution.
