摘　　要：基于IFC格式文件存在数据冗余量大、不易读取的问题,同时浏览器受计算能力和内存限制等影响,对模型的数据组织和加载方式须做出相应调整,即需要使用三维模型轻量化技术对模型进行深度优化处理。对IFC文件进行存储格式的优化以及几何描述参数化和三角化,且相同形状的几何对象不做多次拷贝,相同的构件模型通过坐标的位移(即移动、旋转、缩放等)方式,让模型文件遵循指定的存储规则,可以达到优化存储的目的。Due to the large amount of data redundancy and difficult to read in the IFC format file,the browser is affected by the computing power and memory limitations,so the data organization and loading method of the model must be adjusted accordingly,that is,it is necessary to use the 3D model light quantiza tion technology performs in-depth optimization of the model.We can optimize the storage format of the IFC file,parameterize and triangulate the geometric description,and do not copy the geometric objects of the same shape multiple times.Files follow the specified storage rules to optimize storage.
