Research of Wetland Flood Routing Simulation System Based on OpenGL
基于OpenGL的湿地洪水演进模拟仿真系统的研究*

In the RS, GIS and GPS integrated system of flood resource and wetland entironment of Songnen plain, wetland flood routing simulation system is an important component. The study and development of this simulation system is always a complicated subject. According to the analysis of system target and visualization requirement, OpenGL, that is, the opening internationalstandardofthe3Dimageisexpatiated. OnthebasisofGIStechnology, thesystemisdevelopedbyVisualC++ Program language of object oriented under OpenGL program environment. It realizes the three-dimension display of Zhalong Wetland terrain and flood routing simulation.
