Outline of Final Research Achievements

For everyone, a 3D town model is quite effective in understanding what if this alternative town plan is realized for sustainable development or disaster prevention. Traditionally, urban planners design the town layout by drawing building polygons and contour polygons of equal elevation for a 3d terrain model on a digital map. Depending on these polygons, the proposed system automatically generates a 3D town model placed on a 3d terrain model so instantly that it meets the urgent demand to realize another alternative plan. In our proposal, based on key contours manually drawn, the faces connecting key contours are automatically formed, and then 3D terrain models are created, using the straight skeleton computation for forming faces. After 3D terrain models are generated, 3D house models are placed on these prepared sites. Our methodology greatly saves the laborious manual steps of creating 3D town models.
