DESCRIPTION:A 3D urban model is an important information infrastructure tha
 t can be utilized in several fields\, such as\, urban planning and game in
 dustries. However\, enormous time and effort have to be spent to create 3D
  urban models\, using 3D modeling software such as 3ds Max or SketchUp. In
  our research we will employ automatic generation of 3D building models th
 rough integrating GIS (Geographic Information System) and CG (Computer Gra
 phics). An integrated system is proposed for automatically creating 3D bui
 lding models from building polygons (building footprints) on a digital map
 . Since most building polygons’ edges meet at a right angle (orthogonal 
 polygon)\, a complicated orthogonal building polygon can be partitioned in
 to a set of rectangles. The integrated system partitions orthogonal buildi
 ng polygons into a set of rectangles and places rectangular roofs and box-
 shaped building bodies on these rectangles. This proposal seeks to impleme
 nt a novel approach to 3D building model construction for rapid assessment
  of roof damage and insurance liability in the aftermath of natural disast
 ers.\n\nThe research will achieve two objectives:\n\n- The integration of 
 GIS and 3DCG (3D Computer Graphics) components in a new extension for the 
 ArcGIS platform that generates both simple and complex 3D house models fro
 m building footprints (building polygons).\n- Automated generation of simp
 le and complex roof geometries for rapid roof area damage reporting by len
 gth measurements and area calculations of all roof surfaces. In addition t
 o the application to the assessment of roof damage\, this system can be ap
 plied to BIM (Building information modelling: 3d building model whose part
 s are linked to each attribute\, and by which collision detection between 
 parts can be made).\n\nCo-sponsored by: Okanagan College\n\nSpeaker(s): Dr
