面向地质应用的三维数据模型研究

Research on 3D data model for geological application

对目前国内外常用的两类三维数据模型———基于面的数据模型和基于体的数据模型进行了综述。在此基础上提出了一种新的三维数据模型———基于TIN的不规则五面体模型 ,给出其定义 ,并着重介绍了实现的关键技术。

It is presented that a literature review on the most common 3D data models,which are divided into two classes;surface-based and voxel-based,in domestic and abroad scale.Based on this,a new 3D data model-TIN-based Pentahedral Network data model(PEN) is proposed by the authors.The definition and realization of PEN are also discussed in this paper.
