Paper Abstract

In recent years, the study of 3D spatial models has been developed rapidly, but most of the models are applied to 3D visualization or orebody modeling. They can only provide limited functionality and operations of spatial analysis. To solve this problem, this paper firstly analyzes the characteristics of 3D entities and their demands of modeling, and proposes the method of modeling the exterior surfaces instead of the solid entities themselves using regular volume elements, hence it has offered a new way of modeling 3D entities, which is based on raster technique, in order to make promising preparations for 3D spatial analyses, such as the sunlight analysis. Through preliminary visualization experiments taking the entities with common geometric shapes, simpler and complexer buildings as examples, the feasibility of this modeling method has been proved.
