圆环面截交线投影的参数方程及其在计算机绘图中的应用

The parameter equations of the torus intersection's projection and its application on computer graphing

本文用辅助面法推导出了圆环面截交线投影的参数方程,并应用这一参数方程,在计算机上快速、准确地绘出了圆环面及其有关零件表面截交线的投影。

Auxiliary surfaces are used in the paper to deduce the parameter equations of the torus intersection's projection, with which the projections of the intersections at torus and its relative parts surfaces are drawn by the computer in high speed and accuracy.
