Rule-based procedural modeling of buildings

The demand of virtual 3D models is growing rapidly with the development of city informatization and digitalization. Buildings are essential objects of virtual city. Over the years, researchers have made considerable progress towards developing efficient techniques for generating 3D buildings, however, procedural modeling is still a challenging task because of limitation of data sources and reality requirement restraints. To overcome this problem, this paper introduces a procedural method based on rule sets according to certain criterion available to common building all over the world. We describe the modeling processing based on two-dimension GIS data and digital image. The experiments showed that the presented approach is an automatic and effective method for modeling mass buildings.
