行业基础类 (IFC) 被广泛认为是建筑信息模型 (BIM) 的一个有前景的标准。 IFC数据可以使用IfcOpenShell、Java标准数据访问接口（JSDAI）等多种开放工具包进行处理，极大地支持了BIM研究和技术开发。然而，IFC 数据并不直观，需要经过培训才能完全理解。作为几乎所有 IFC 数据的核心，理解几何表示对于大多数 BIM 研究和技术开发至关重要。官方的IFC模式规范对IFC中的实体和属性提供了详细的解释，这有助于获得这样的理解。然而，理解规范中的解释需要一定的知识和背景。为了更容易理解 IFC 数据并促进更广泛地采用基于 IFC 的 BIM，本文在游戏模拟中以第一人称视角创建了所选建筑、工程和施工 (AEC) 对象的基本 3D 表示形式的交互式可视化。交互式模拟可以帮助人们以直观、快速的方式理解IFC中的3D几何构造和表示，有望实现与阅读规范的传统方式相当或更好的知识保留。 14 名志愿者对可视化进行了测试，并与阅读 IFC 模式规范进行了比较。基于实验的调查表明，与阅读规范相比，基于游戏模拟的可视化明显更容易理解，并且花费的时间明显更少。
Industry foundation classes (IFC) is widely accepted as a promising standard for building information modeling (BIM). IFC data can be processed with many open toolkits such as IfcOpenShell and java standard data access interface (JSDAI), which greatly supports BIM research and technology development. However, IFC data is not intuitive and requires training to understand it fully. As the core of almost any IFC data, understanding geometric representation is critical in most BIM research and technology development. The official IFC schema specifications provide detailed explanations of entities and attributes in IFC, which are helpful for gaining such understanding. However, understanding the explanations in the specifications requires certain knowledge and background. To facilitate an easier understanding of IFC data and to promote a wider adoption of IFC-based BIM, in this paper, an interactive visualization of the formation of fundamental 3D representations of a selected architecture, engineering, and construction (AEC) object was created in game simulation in a firstperson view. The interactive simulation can help people gain understanding of 3D geometric formation and representation in IFC in an intuitive and speedy manner, which is expected to achieve retention of such knowledge comparable to or better than the conventional way of reading the specifications. The visualization was tested by 14 volunteers in comparison to reading the IFC schema specifications. A survey based on the experiment showed that the game simulation-based visualization was significantly easier to understand and took significantly less time to understand comparing to reading the specifications.
