| Abstract: | 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. |
