| 摘 要： | 结合非层状矿体特点,提出带控制线的平行轮廓线三维矿体重建算法.该算法通过人机交互指定轮廓线上的特征点形成若干条控制线,使得最小跨距三角网在指定的线之间生成;并提出添加辅助线的分支处理方法.在对复杂形态的矿体实体建模和分支处理问题上进行了编程和实验.实验结果证明该算法简单、高效和实用,从底层开发的三维建模软件可提供相关矿山用户应用.

| Abstract: | An algorithm of minimizing span length with control lines was developed based on features of intricate orebody planar contours. The algorithm allows user to specify control lines so that triangular net could be built among those lines. Also, an auxiliary line algorithm for solving branching problem was given. Programming and testifying have been done. The results prove that those algorithms are simple, highefficient, and useful for developing 3D modeling software of mine. |
