摘要
根据地下水数值模拟的实际需要,建立一种基于三棱柱体体元的数字地层模型,给出相关的剖切算法和与之对应的数据结构,实现了复杂地质体三维任意剖切和显示等各项功能。实践证明,它能够满足水文学应用的要求。
In the course of groundwater numerical modeling, section of various angle is needed to ascertain some parameter values generally. In this paper, a method based on Triprism is used to build a stratum model and related algorithms of sections and incisions and corresponding data structure are given. Various 3D visualization functions of complex geological objects, including random section and display are fulfilled. It is proved that the method can meet the need of hydrology application.
