| Abstract: | This paper presented an algorithm for 3D open-pit model generation based on constrained Delaunay triangulation.Combining with the characteristics of stope data,the algorithm inserted the step-lines and characteristic lines of terrain into triangulation net.The 3D open-pit model could improve the precision and approach the actual stope.The 3D display result was obviously improved.Through precise 3D visualization,engineers of mine can observe terrain and stope arrangement straightly in order to make scientific decision for the project of mine.The algorithm could effectively deal with all kinds of instances,and be implemented by programs easily,and accord with requirements of the project. |
