摘要：">Due to the data characteristics of the 3D geological model of digital mine, the "T-F" (Visible is True or False) hidden line removal algorithm isproposed on the basis of depth sorting. The "T-F" algorithm first marks outthe visible segments of edges with T or F on the basis of the hiding relationship between edges and planes. Then, we merge the visible segments of every edge to realize the goal of blanking. Finally, the proposed algorithm issuccessfully applied to 3D geological model cases on the platform of Microsoft VS2008. © 2011 Asian Network for Scientific Information.
