contour forming

According to spatial distribution feature of ore body, the special 3D data model and data structure have been designed. The method of establishing spatial 3D data structure by means of 2D contour lines forming 3D shape and using Morton codes is introduced.

本文根据地矿的空间分布特征，设计出专用的三维空间数据模型及数据结构，介绍了由二维轮廓线构造三维形体，Morton码建立空间三维数据结构的方法。
