Southern China is vulnerable to torrents, atmosphere and other disasters. In order to capture the effects of mountain torrents and air pollution quickly and accurately, this paper proposes a three-dimensional dynamic flooding simulation algorithm for environmental disasters on the needs of agricultural information projects.Based on that, according to the different data collected by sensors, combined with Unity 3D modeling technology,the three-dimensional dynamic flood submergence model and PM2.5 three-dimensional visualization model are constructed respectively. They can make data dynamically ...
