摘　　要：在建筑施工图纸的基础上,选择使用AutoCAD建模软件生成的DXF文件作为模型的数据文件。通过对数据文件的组织结构进行分析,对文件中的点坐标和实体坐标信息通过VC++编程读取,获取文件中对建模有用的信息。重点讲述如何读取数据文件,并通过坐标转换,生成三维坐标系,根据尺寸链接得到全部点和边的坐标,并通过三维坐标点的信息结合VC++编程和OpenGL图形库实现建筑物的三维重建。On the Basis of architectural working drawing,the article chooses to use the DXF files which are made by AutoCAD modeling software as the data file of the model.It makes an analysis to the organization structure of the file,which reads the coordinate information of the points and the entities by VC＋＋ programming to get the useful message.Its key point are how to read the data files,by coordinate transformation to get three-dimensional coordinate,and get all the coordinates of the points and edges,by which it eventually realizes the two-dimensional reconstruction of the architecture combined with VC＋＋ programming and OpenGL graphics library.
