GIS and CG Integrated System for Automatic Generation of 3-D Urban Models

such as, simulator for landscape evaluation, community planning and civil engineering. However, in order to realize 3-D urban model, the enormous time and money have to be consumed to design the model and to acquire the data for the model. In this paper, we propose the system to generate 3-D Urban Models automatically, utilizing and integrating GIS and CG. The programs have been developed to process the 2-D GIS information. Another program on the side of 3-D CG receives the processed data and generates 3-D Urban Models automatically.
