Geographic data visualization is an important research area of Web Geographic Information System (GIS). Owing to the detailed subassemblies and exhaustive knowledge database, building information modeling (BIM) plays an important role in geospatial research and industries. The integration of BIM and GIS contributes to the smooth visualization, quick construction, and efficient management of geographic data. However, there are very few methods that can yield high-efficiency data transmission and visualization for complex BIM models while maintaining the integrity of the internal subassembly structure and attributes. To overcome this issue, this paper proposes a 3D Tiles-based visualization method for complex BIM models on the Web-based 3D model viewer. This method is adopted to partition the BIM model according to its assembly without simplifying the BIM model, by using a tiling method for 3D models based on a degraded R-tree, which accounts for the size of tiles. Subsequently, we introduce the “Mask Filter,” a level of detail method that is used to layer the BIM model. Conducting a series of contrast experiments, the result indicates that this method is efficient and feasible, which significantly improves visualization performance of complex BIM with mass data in the geospatial scene and facilitates the integration of Building Information Modeling and Geographic Information System.

基于 3D Tiles 的 Web 上复杂 BIM 模型的高效可视化方法

地理数据可视化是Web地理信息系统（GIS）的一个重要研究领域。由于详细的组件和详尽的知识数据库，建筑信息模型 (BIM) 在地理空间研究和工业中发挥着重要作用。BIM与GIS的融合有助于地理数据的流畅可视化、快速构建和高效管理。然而，很少有方法可以为复杂的 BIM 模型产生高效的数据传输和可视化，同时保持内部组件结构和属性的完整性。为了克服这个问题，本文提出了一种基于 Web 的 3D 模型查看器上复杂 BIM 模型的基于 3D Tiles 的可视化方法。这种方法是在不简化BIM模型的情况下，根据其装配对BIM模型进行分区，通过使用基于退化R树的3D模型的平铺方法，其中考虑了平铺的大小。随后，我们介绍了“蒙版过滤器”，这是一种用于对 BIM 模型分层的详细方法。通过一系列对比实验，结果表明该方法有效可行，显着提高了复杂BIM在地理空间场景中的海量数据可视化性能，促进了建筑信息模型与地理信息系统的集成。” 一种用于对 BIM 模型进行分层的详细级别方法。通过一系列对比实验，结果表明该方法有效可行，显着提高了复杂BIM在地理空间场景中的海量数据可视化性能，促进了建筑信息模型与地理信息系统的集成。” 一种用于对 BIM 模型进行分层的详细级别方法。通过一系列对比实验，结果表明该方法有效可行，显着提高了复杂BIM在地理空间场景中的海量数据可视化性能，促进了建筑信息模型与地理信息系统的集成。
