Research on 3D Buildings Model Based on RBC Theory

摘要

The expression of 3D model of buildings is the key when constructing a 3D city model. However, the modeling methods are still being studied due to the variety and complexity of building spatial modality. The theory of Recognition by Components studies how intricate object can be broken down into recognizable basic geometric units (i. e. , Geon). Based on this theory, this paper discusses its importance on the recognizability, standardization and fast modeling of building model, and emphases are loaded on the structure and classification of basic geometric units that constitute the 3D model of buildings and on how the model of intricate building is established in different levels of details.
