| Abstract: | Based on the study on both construction of 3 dimensional(3D) visualization of scene and real time dynamic simulation of flood routing,this paper proposed a method of 3D simulation system to simulate flood submergence.Using hydrological mathematical model is the core of the research on visualization of flood protection.This method was presented taking Jiujiang city as an example,which is along Yangtze River.3D terrain scene of Jiujiang city was constructed.Under this simulation scene,analysis of flood routin... |
