| 摘 要： | 提出用重影线法求解两一般位置平面相交求交线判别可见性的新方法．它是对两直线在某投影面上投影重影的现象进行分析，从空间角度认识其几何位置，由此得出重影线的定义，将其用于解决两一般位置平面相交问题，可直接求交线，并随即确定可见性．

| Abstract: | This paper proposed a new method to find the intersection line and determine its visibility of two general position planes using overlapped projection lines. The overlapped projection of two lines projected on one plane is analyzed and the intersectional graphic position is determined from the view point of space so as to find the intersect line and the determine its visibility. |

| Keywords: | overlapped projection lines intersection line visibility |
