“…However, extant studies do not focus on dynamically loading, and this makes it difficult to load large IFC files on the web browser. Recently, a few studies also examined dynamically loading of 3D data [19][20][21][22][23][24]. For example, Shen et al [19] constructed a game scene by using the geometric data of the BIM model.…”

“…Wang et al [23] proposed a fast dynamic transmission method for 3D cloud data. Li et al [24] presented a system for the progressive compression and transmission of a 3D model with WebGL. However, the aforementioned transmission methods generally optimize transmission speed via the optimization of data structure and algorithm, and thereby ignores spatial information.…”

Industry foundation classes (IFC) is an open and neutral data format specification for building information modeling (BIM) that plays a crucial role in facilitating interoperability. With increases in web-based BIM applications, there is an urgent need for fast loading large IFC models on a web browser. However, the task of fully loading large IFC models typically consumes a large amount of memory of a web browser or even crashes the browser, and this significantly limits further BIM applications. In order to address the issue, a method is proposed for dynamically loading IFC models based on spatial semantic partitioning (SSP). First, the spatial semantic structure of an input IFC model is partitioned via the extraction of story information and establishing a component space index table on the server. Subsequently, based on user interaction, only the model data that a user is interested in is transmitted, loaded, and displayed on the client. The presented method is implemented via Web Graphics Library, and this enables large IFC models to be fast loaded on the web browser without requiring any plug-ins. When compared with conventional methods that load all IFC model data for display purposes, the proposed method significantly reduces memory consumption in a web browser, thereby allowing the loading of large IFC models. When compared with the existing method of spatial partitioning for 3D data, the proposed SSP entirely uses semantic information in the IFC file itself, and thereby provides a better interactive experience for users.
