Research on Simplification Method of Building 3D Models Based on Radial Contraction
This paper utilizes a thought experiment method of virtual particle emission stopping on the exterior surface of a building in three-dimensional space to establish a simplified shell of a three-dimensional model of the building.This method generates a simple model grid,has a strong platform adaptability and high web running efficiency.It is a new method for extracting shells from complex single surface models.The principle is clear,the degree of automation is high,and the model grid is simple.It can significantly improve the simplification efficiency and scene fluency of city level large-scale scene models,and provides a new technical solution for integrating a large number of BIM models into the CIM platform.
