“…OCCT can be involved in the whole process of information visualization, but in this study, it mainly functions at step 1 and step 2 for reading and processing IFC geometries into buffers that are to be sent to the GPU API. Buffers can be sent to OpenGL in a desktop-based system or WebGL in a webbased system [63,64]. These buffers contain primitive geometric information that is to be displayed on a computer screen; therefore, extracting and interpreting these buffers is vital to this study.…”

“…These shape objects contain very primitive elements of geometry, referred to as triangulation elements in OCCT. They are originally supposed to be sent to the GPU for visualization [64]. These shape objects were closely examined in this study, and a method was developed to rebuild B-Rep from these primitive elements.…”

The development of a smart city and digital twin requires the integration of Building Information Modeling (BIM) and Geographic Information Systems (GIS), where BIM models are to be integrated into GIS for visualization and/or analysis. However, the intrinsic differences between BIM and GIS have led to enormous problems in BIM-to-GIS data conversion, and the use of City Geography Markup Language (CityGML) has further escalated this issue. This study aims to facilitate the use of BIM models in GIS by proposing using the shapefile format, and a creative approach for converting Industry Foundation Classes (IFC) to shapefile was developed by integrating a computer graphics technique. Thirteen building models were used to validate the proposed method. The result shows that: (1) the IFC-to-shapefile conversion is easier and more flexible to realize than the IFC-to-CityGML conversion, and (2) the computer graphics technique can improve the efficiency and reliability of BIM-to-GIS data conversion. This study can facilitate the use of BIM information in GIS and benefit studies working on digital twins and smart cities where building models are to be processed and integrated in GIS, or any other studies that need to manipulate IFC geometry in depth.

“…However, some studies such as [59] that use simulation tool with no performance measures are considered empirically validated in this study, because these kinds of studies have some simulation data. On the other hand, we identified 23 (41.82%) studies that are empirically validated, which are [12]- [19], [21], [22], [49]- [51], [57]- [59][31]- [33], [35], [39], [41], [52].…”

Of recent, Building Information Modelling (BIM) has become an influential paradigm for the development of better project delivery practices to improve construction and operational efficiencies. In the last 6 years, a significant number of studies have been published on the integration of BIM in Internet of Things (IoT). This paper aims to examine the general research productivity, demographics, and trends shaping the research domain. Hence, the paper will also help to identify, categorize, and synthesize important studies in the research domain. In doing so, we adopt an evidence-based systematic mapping methodology to ensure the coverage of key studies through a systematic and unbiased selection and evaluation process which results in the final selection of 55 relevant studies. The results of the mapping study show that the research on the integration of BIM in IoT is gaining more attention in last 6 years with stable and consistent publication output. Prominent application domains, validation methods, contribution facets, research types, and simulation tools in the field of study were identified and presented. Five research types were also identified, i.e. solution proposal, experience paper, evaluation research, validation research, and opinion paper, with solution proposals getting more research attention. In general, the overall demographics of the research domain were presented and discussed.

“…The modelling of IBIM cloud data is the basis for optimizing the data collection and management of 3D models. The relevant research mainly focuses on the reverse engineering of BIM from point cloud, as well as the virtual reconstruction and simulation of existing buildings [17][18][19][20]. Based on point cloud technology, Ma et al [21] developed an automatic O&M method for datacenters, which excels in antiinterference and data storage.…”

The operation and maintenance (O&M) of intelligent building information model (IBIM), as an important aspect of modern building informatization, plays a critical role in the construction of smart cities and the renovation of modern buildings. Due to the complex structure and sheer size of IBIM data, the O&M system of IBIM faces a huge workload and a high cost. Based on cloud computing, this paper proposes an O&M strategy for IBIM data, which meets the needs for stable management of massive data, enables three-dimensional (3D) collaborative visualization of building information model (BIM), improves the efficiency of data storage, scheduling, and O&M. Firstly, the basic structure of IBIM data was standardized according to The Industry Foundation Classes (IFC) (ISO 16739-1:2018). Then, the features were sampled from the standardized IBIM cloud data. After that, the storage data were subject to routing, coding, matching feature compression, and adaptive attribute clustering. On this basis, an optimization model was established for the storage structure of IBIM cloud data. Finally, a batch feature extraction method was designed for 3D structure distribution of job-based 3D cloud storage model. The proposed strategy was proved effective through experiments. The research results provide a reference for applying 3D cloud storage model in other fields.
