Abstract: With the expansion of three-dimensional map applications, the technictue of three-dimensional modeling is more sophisticated. For study of three-dimensional visualization of the campus, the paper expounded three-dimensional modeling of campus library based on ArcGIS, including those based on symbolic modeling, based on plug-in modeling and based on DEM modeling. Furthermore, the advantages and disadvantages of each modeling method were discussed.
