摘要:BIM软件中获取管线排布信息的过程较为复杂，本研究基于Unity3D提出了一种两次投影的方法，通过BIM云平台功能模块的开发应用，对机电管线排布信息的获取方法进行优化。通过获取物体的顶点坐标，对顶点坐标进行两次投影，根据投影后的坐标快速准确地计算出三维世界中顶点之间的距离，通过编程实现在终端设备上动态显示管线信息。运用此方法可以实现管线排布信息的信息化及可视化，为现场施工与设计意图保持一致提供便利，为管线工厂预制加工提供准确信息。
Abstract: It is too complicated to acquire pipeline layout information in BIM software. Based on Unity3D, a method of double projection is proposed in this paper. Through the development and application of BIM cloud platform function module, the method of obtaining electromechanical pipeline layout information is optimized. By obtaining the vertex coordinates of the object and projecting the vertex coordinates twice, the distance between the vertices in the three-dimensional world can be calculated quickly and accurately according to the projected coordinates, and the pipeline information can be displayed dynamically on the terminal equipment through programming. By using this method, the information of pipeline layout can be achieved, which provides convenience for the consistency of site construction and design intention, and provide accurate information for prefabrication of pipe in factory.
