说明：  海量散乱点的曲面重建算法研究 本文提出了一个对大量密集点集进行空问划分的算法，给出了相应的数据结构，提高了海量数 据的处理效率，并对Hoppe等人提出的三角网格面重建算法进行改进，能更好地进行有界曲面以 及带尖锐棱边曲面的重建
(Massive points scattered surface reconstruction algorithm proposed in this paper, a large number of dense point set for space division algorithm, the corresponding data structure, improve the efficiency of mass data processing, and Hoppe et al proposed triangulation cell surface reconstruction algorithm can be better bounded surface and sharp edge with surface reconstruction)
