A Web-Based Approach for the Efficient Management of Massive Multi-source 3D Models

Effectively managing extensive, multi-source, and multi-level real-scene 3D models for responsive retrieval scheduling and rapid visualization in the Web environment is a significant challenge in the current development of real-scene 3D applications in China. In this paper, we address this challenge by reorganizing spatial and temporal information into a 3D geospatial grid. It introduces the Global 3D Geocoding System (G3DGS), leveraging neighborhood similarity and uniqueness for efficient storage, retrieval, updating, and scheduling of these models. A combination of G3DGS and non-relational databases is implemented, enhancing data storage scalability and flexibility. Additionally, a model detail management scheduling strategy (TLOD) based on G3DGS and an importance factor $T$ is designed. Compared with mainstream commercial and open-source platforms, this method significantly enhances the loadable capacity of massive multi-source real-scene 3D models in the Web environment by 33 %, improves browsing efficiency by 48%, and accelerates invocation speed by 40%.
