Virtual visual simulation of urban lakes based on OpenSceneGraph

With the development and wide application of virtual reality in various industries, three-dimensional virtual visual simulation technique has become an important presentation manner in water conservancy project information management. After the relevant support technologies such as GIS, Remote sense, computer graphics and water rendering are deeply researched, this paper presents a development framework about three-dimensional virtual visual simulation system (3D VVSS) of large-scale urban lakes. Combining with the large-scale ecological water network scheduling project of Dong Lake in Wuhan city of Hubei province and OpenSceneGraph platform, a 3D VVSS of urban lakes is constructed, which can provide virtual roaming, information query, real time monitor information of water quality displaying, etc. Finally, some optimized measures are discussed to improve running speed and efficiency of the VVSS.
