In order to grasp the dynamic change of smart city environment more comprehensively,the automatic simulation system of smart city environment dynamic change based on virtual reality tech-nology is studied.Utilize the GIS data layer to obtain spatial data of the smart city environment,input the 3D CA smart city environment dynamic change model,and generate the dynamic change results of the smart city.Store the results in the VR scene database to construct a realistic virtual scene of dynam-ic changes in the smart city environment.Users can interact with virtual scenes and showcase changes in the smart city environment through roaming and interactive design.The experimental results show that the scene has high stereoscopic accuracy,realistic visuals,fast and smooth loading time,and can simu-late changes in buildings and land in different years,with excellent application effects.
