共母线直纹曲面投影交线的计算与特征分析

Calculation on Projection Ine of Ruled Surfaces and Analysis on Curves Features

讨论了共母线直纹曲面交线的解析计算,通过相贯线的投影曲线方程的建立,计算得出相关曲线方程,结合实例详细分析了投影曲线的各种形状特征,以便于图形的计算机可视化实现。

Discusses the resolution methods of the intersection line of the ruled surfaces, sets and calculates the relative curve equation the curve projection equation of the intersection line, at last, analyses the different kinds of the features of the projection curves in order to the computer visualization of graphic.
