Abstract: With the development of virtual reality technology, 3D modeling and visualization technology has been used in the smart city. In this paper, 3ds Max software is used to build modeling of campus buildings, roads, trees and other features, and visualization in the SuperMap software. Taiyuan Normal University is as an example, this paper researches the key techniques of data acquisition, data processing, 3D modeling and visualization, especially focuses on particle effects and its application in the rain, snow, fireworks effects, which really reproduce the three-dimensional environment of the campus.

Key words: 3D modeling, visualization, particle effects, 3ds Max, SuperMap
