Organization and Scheduling of Indoor Three-Dimensional Geometric Model Based on Spatial Topological Relation

Based on the analyses of unit functions and unit function types of the interior space, an interior-space network-topology model that contained semantic information, supported path analysis, and fully expressed the topological logic of the various parts of the interior space was constructed after considering the demand for three-dimensional (3D) high-quality space navigation rendering, and limitations in personal mobile platform resources and computing power. In addition, by accurately determining the regions and topological logic of the interior space, strategies for space division and organization and strategy adjustment of geometric models based on topological relations of the interior space were explored, achieving the goal of dynamic interruption and elimination of interior models. The applicability, feasibility, and effectiveness of the proposed model were verified by performing actual tests using personal mobile platforms. The results indicated that the methods proposed in this study could interrupt and eliminate geometric models in real time, significantly reducing the number of models rendered and enhancing data transmission and rendering efficiency. This method provided reliable data and assurance concerning the visualization and rendering of high-fidelity 3D models.
