直母线螺旋面三维真实感图形的显示

The display of three dimension realistic drawing of helix surface with straight line element

建立了直母线螺旋面的数学方程式，对其三维真实感图形的计算机显示进行了探讨，提出了直母线螺旋面的消隐和真实感处理方法．用Ｃ＋＋编程实现了直母线螺旋面的真实感处理。

The mathematical equation of helix surface with straight line element is set up.The computer display of three dimensional realistic drawing of helix surface is studuied. The method of hidden line removing and realistic processing are proposed.The realistic processing of helix surface is executed with C ++ program,and the example of computer drawing is shown in this paper.
