摘　　要：以 Auto CAD作为图形输入环境 ,以 STL、DXF等格式的图形文件作为数据交换接口 ,对图形进行交互式立体显示 .通过分析文件格式 ,在 Visual C++6 .0编程环境下获取文件中的二、三维图形信息 ,对其中基于回转体的二维图形进行三维旋转造型 ,生成三维实体数据 .并应用 Open GL 图形处理技术对输入的三维图形实现真实感显示 ,进行变换、光照。The paper describe a method to carry out interactive three dimensional display of figure using graphic files such as STL, DXF as data exchange interface,and taking AutoCAD as graphic inputting environment. By analyzing document format and with visual C++6.0 programming environment, two dimensional or three dimensional graphical information can be obtained from files. Three dimensional entity data can be generated by running three dimensional turnover molding of planar figure (which is based on solid of revolution). Afterward we can apply technology of OpenGL graphic processing on three dimensional figure afferenting module, and go on with processing of transform, illumination and material disposition.
