| 摘 要： | 针对直线与平面相交,直线可见性的判断问题进行研究.首先从平面的投影特点入手,将平面分别设定为正面、背面两面,讨论了平面图形各顶点投影顺序与平面正面、背面投影的内在规律.阐述了空间直线与平面相交,彼此相对位置的不变性.提出并论证了各种位置直线与平面相交,直线在相邻两投影面上可见性的投影规律.它与用重影线法求直线与平面相交交点相结合,为直线与平面相交直线可见性判断提供了一种新方法.

| Abstract: | This article aims to study the intersection visibility of line and plane.Planes were set as two faces of front and backs from the point of projection character of a space plane.The projection sequence of plane graphs apex and relationship of the sequence and plane faces were discussed.The intersection visibility rule of a line and general plane was concluded and a new judge method on intersection visibility of them was also put forward in this paper. |
