摘要:为了在新冠疫情期间减少人员接触，并鼓励开发企业利用互联网、虚拟现实(VR)和直播售楼等非接触方式开展线上楼盘展示，提出了以BIM模型为基础，将BIM模型的IFC标准转换为适用于网络传输的3D Tiles标准。该方法主要分为IFC-OBJ、OBJ-glTF和glTF-3D Tiles三个步骤，并选用开源平台Cesium作为加载BIM模型的框架。实现了BIM模型在Web端的快速加载，并且减少了几何信息和属性信息丢失的情况，为开发企业提供新的营销方案。
Abstract: To reduce personnel exposure during the COVID-19, and encourage development enterprises to use the Internet, virtual reality(VR)and live sales and other non-contact ways to carry out online real estate display. It is recommended that based on the BIM model, the IFC standard of BIM model is transformed into 3D Tiles standard for network transmission. This method is mainly divided into three steps: IFC-OBJ, OBJ-glTF, and glTF-3D Tiles. The open-source platform Cesium is selected as the framework to load the BIM model, which realizes the quickly loading of BIM models on Web, and reduces the loss of geometric information and attribute information, and provides a new marketing scheme for development enterprises.
