Abstract: In order to better display the water environment, some water environment modeling methods were proposed in this paper. In addition, water presentation pattern, water level and water duality changing presentation methods were introduced. By using some vega inbox functions, such as pathing, navigator and motion models, the automatic roaming and interactive scene roaming are achieved. Finally, the callback method is used to display multiple windows, and this method can present multiple scenes simultaneously. The above methods and functions have been successfully applied to urban water environment simulations and achieved good results.

Key words: Water environments simulation, 3D model, Roaming, Multi-window
