【摘要】 三维地质模型在计算机中的数据表达就是三维地质模型的数据模型，它具有确定性、可视性和可修改性的特点。文章介绍了表达三维地质模型的几种典型的三维数据模型，即体元充填模型、 TIN表面模型、矢量模型、混合模型和面向对象的模型，体元充填模型根据采用的体元又可分为 4个亚类。更多还原

【Abstract】 Data expression method of 3D geological model in computer is data model of 3D geological model . It has characters of certainty, visualization and modifiability. The paper introduces typical data models of expression 3D geological model, including voxels fill, surface TIN, vector, hybrid and object oriented, and voxels fill model can be classed into 4 sub－ sorts.更多还原
