剖分生成的剖面效果不理想。本文结合视觉化工具函式库（VTK）的切割接口，提出了对建

线求交的方法。实际切割效果表明该算法在对三维地质结构模型进行切割时，生成剖面的速10

out a cutting algorithm that can cope with the 3D geological structure model which has a bad

quality. The cutting algorithm main including two ways，one is reorganizing the intersecting line，25

another one is computing intersection by vertical line. The actual cutting experiments show that

the cutting algorithm can deal with the 3D geological structure models，the sections are produced

faster and have a high quality.
