三维地质模型分析概述

由于三维地质建模需要对矿体的品位等属性信息进行详细的描述,所以三维地学建模须采用基于体元的方法建模,也可以由表面模型栅格化为体元模型。综述了现在常用的三维地质建模的一般方法,实体模型、四面体、块体模型、结构实体几何、似三棱柱等,并对各自的优缺点进行了分析,着重介绍了基于体元的建模方法,可为三维地质建模初学者提供一定的参考。

Review of Three_dimensional Geosciences Modeling

As the 3D geological modeling of the ore body need the grade and the other attribute information,it must based on volume element,or on the rasterization surface model.It has provided a clear overall picture of all those methods. The solid model,tetrahedral model,block model,constructive solids geometry and similar triangular prism model,and their advantages and disadvantages,and has given a benifical reference to research and develop some new sculpt methods for 313 geosciences modeling.
