CAD-Based 3D Semantic Modeling of Putrajaya
In this research project we are addressing /ow cost 3D city modeling techniques. 2D existing highly detailed CAD data with lots of layers and rectified perpendicular symmetric photos of intricate constructions are used to generate the 3D models of Putrajaya in CityGML and CityServer3D. Our 3D models are in LOD2.5 plus higher Level of Realism (LoR). Texture enhancement methods such as texture left-right or up-down symmetrical transformation and higher radiometric adjustment for raised surfaces and Dynamic Pulse Function are used in this research based on facet situation and our observation on the form of tessellation on the fagade textures. The problem of missing faces of polyhedrons or polygons and missing objects have been solved and described in this paper in CityGML and some Code-Lists defined for complex and intricate structures such as domes of the Putra Mosque or Court of Justice buildings in Putrajaya.
