摘　　要：在工业测量领域中,由于测量对象千差万别,离散的测量数据很难进行描述和分析,而可视化技术能有效地克服这一缺点。本文研究了在VB平台上进行OpenGL图形开发的方法,实现了DXF文件的读取与显示、多种3维模型的绘制以及交互操作功能,为工业测量数据实现3维可视化分析提供了一个方便、快捷、高效的途径。In the field of the industrial measurement,it is difficulties to describe and analyze the disperse measured data for the different measuring object.However,the visualization technique can overcome the defect effectively.In this paper,the methods of OpenGL graph development based on VB were researched.The reading and display for DXF files were achieved,the draw function and the interoperate function for the various 3D models were realized.All these provided a convenient,shortcut and efficient way to implement the 3D visualized analysis for the industrial measuring data.
