摘要
本文推导出来的圆环面与圆锥面相贯线投影的参数方程,完全满足计算机绘图的要求.用该参数方程编程,除了赋值不同外,对绘制圆环面与圆柱面相贯线的投影具有通用性.
The parameter equation derived in this paper, for the projection of the traverse line of the ring surface through the cone surface, meets well the demand of the computer graphing. The program devloped by such a parameter equation presents universality in applying it to drawing the travers line projection of the ring surface through the cylingder surface with difference only in parameter value assingment.
