【摘要】 阐述了中线加断面生成巷道体三维建模方法,然后对相交情况下的巷道体进行布尔运算生成贯通的巷道。针对建模过程中存在的巷道断面的三维坐标转换、三角网格的生成、巷道体之间的布尔运算等关键技术,提出了具体的解决方法,并给出了最终的实验结果,实验验证了此三维建模方法的可行性。更多还原

【Abstract】 The essay elaborates the three dimensional modeling method of median line adding the cross section,and then makes the laneway entities run-through by Boolean operations when they intersect.Proposing the concrete solutions as to the essential technology of the modeling process in three dimensional coordinates transformation of cross section,triangle grid production and Boolean operations between the laneway entities.Finally,it produces the final test result.The experiment confirms the feasibility of three dimensional modeling methods.更多还原
