%X As OpenGL cannot realize dynamic hidden line removal in a dashed way, the real-time hidden line removal is a big problem while designing the three dimension dynamic geometric software. Based on the OpenGL system and the present hidden surface removal technology - depth buffer algorithm, the overlap of two lines and the rotation angle of the viewpoint about the local coordinate system were computed to achieve the dynamic hidden line removal in a dashed way. Furthermore, when a line is hidden by a surface, and a curve is hidden by plane or surface, this method can also be applied.
