摘要
提出了构建三维地形及线路整体模型的一种方法 ,该方法的特点是在拼合地表曲面和线路表面时采用了分治算法 ,且可将面与面的求交计算简化为线段间的求交计算 ,故计算工作量较少且速度快 .在此基础上 ,通过集成AutoCAD及 3DS即可达到对铁路线路进行三维造型的目的 .实际应用表明 。
A new method for establishing three dimensional model overall terrain and railway line is presented. The specificity of this method is using a divide and conquer algorithm to merge the terrain and railway line’s surface and to simplify calculation of intersection of surfaces to intersection of lines, so the method has the advantages of less calculation and higher speed.The 3D modeling for railway line can be realized based on integration of 3DS and AutoCAD. The practical application shows that the images made from the model generated by the method can realistically foreshow the figure of railway line to be constructed.
