基于面元模型的矿体三维可视化模型研究

摘要

对矿体三维建模中的常用面元模型—TIN(不规则三角形网)模型进行了介绍,并对TIN模型的实现算法一逐点插入算法进行了算法描述；最后说明了TIN模型中所存在的问题与不足,以及当今矿体建模中为解决这一问题所采取的方法.%This paper introduces the TIN model which is a penal model used in three-dimensionalmodeling of ore bodies and describes the incremental insertion algorithm that is used to implement theTIN model. Lastly, it discusses on some questions that is existed in the TIN model.
