| 摘 要： | 3DXML文件格式是一种重要的轻量化CAD数据格式,通过对3DXML文件格式的分析,论述了一种基于MSXML解析器的文件解析技术。这种解析方式可以快速提取3DXML文件中的重要信息,通过对几何及属性信息的重构,建立整个装配体场景,使用文件中的多分辨率模型,可以提高较大模型的渲染速度。最后给出了基于3DXML文件格式的轻量化CAD浏览器的应用实例。

| Abstract: | 3DXML file format is an important lightweight CAD data format.Through analyzing 3DXML file format,an approach to parse 3DXML file with MSXML is presented,which can be used to get important information from 3DXML file quickly.According to reconstructing the geometry and attribute information,the whole scene of assembly will be built.Using the LOD models,the speed of rendering will be accelerated.Finally,a lightweight CAD model viewer based on 3DXML file format is given as an example. |
