spatial data visualization is one of the research hotspots in the field of 3dgis. The interactive visualization of engineering analysis data is realized on avs platform by using the simulation result data of engineering analysis software and visualization development package avs/express, combining data glove and position tracker. Engineering analysis data and realistic models are combined, and virtual reality technology is used to provide interactive visual environment for users. On this basis, with the help of virtual reality technology and opengl, a 3dgis prototype system is implemented, which has the functions of realistic visual expression of spatial data, real-time roaming of 3d scenes, interactive query, etc. The 3d model is downloaded to the client for display. Complex operations and simulations are performed on the server, thus realizing the separation of the server-side assembly model and the client-side display model. Thus, the quality of engineering design is greatly improved, and a new visual realization mode of engineering analysis data is provided.
