In order to solve the problems of low efficiency and insufficient accuracy of dynamic simulation in urban landscape design,a dynamic simulation model of urban landscape based on virtual reality technology is proposed.Based on the Mongo DB database,the overall framework of the dynamic simulation model of urban landscape virtual reality was constructed,and the three-dimensional design of urban landscape was carried out in combination with Open GL.In order to ensure the accuracy of the dynamic simulation of urban landscape,the Rank transform was combined to match the urban landscape units and optimize the camera parameters.Through the relative error and the performance test of the simulation model,the dynamic simulation model of urban landscape based on virtual reality technology has higher accuracy and faster corresponding time.By improving the model,the dynamic simulation quality of urban landscape design can be effectively improved and the work efficiency can be improved.
