| Research Abstract |
Once urban environment is projected into 3-D virtual space, it can be modified and utilzed for various simulations. 3-D urban model in virtual space is the important information infrastructure that can be utilized in several fields, for example, landscape evaluation urban planning civil engineering architecture, disaster prevention simulation, etc. In addition disclosure of information about public projects to the public in order to encourage their participation in urban planning is a new application area where 3-D urban model can be of great use. So it is necessary to create objects in 3-D urban model such as buildings, roads, bridges, towers and other utilities efficiently. The manual creation of the shapes and the texture mapping for these objects require lots of labor and time. Therefore, we aim at generating 3-D urban models, especially building models automatically. In this research, we propose the system to generate 3-D Urban Models automatically by the Integration of CG and GIS. The GIS application has been developed to process 2-D GIS information, using GIS software component. Another program that controls 3-D CG software receives the processed information and generates 3-D Urban Models automatically
