摘　　要：介绍了三维空间数据场在虚拟仪器中的应用 ,分析了三维图像获得广泛应用的原因 ,讨论了建立三维空间数据场的基本方法 ,及图形图像加速处理的常用手段 ;详细论述了如何利用OpenGL技术 ,建立三维空间数据场及其实现方法。通过对效果图的对比分析表明 ,该方法所建立的三维图像具有良好的真实感 ,运行速度快 ,而且交互性能强。The application of three dimensional space data field in virtual instrument is presented, the reason why three dimensional images can be applied widely is analysed, and the basic methods of the construction of three-dimensional space data field and the typic means of the accelerated processing of figures and images is discussed. How to construct three-dimensional space data field by using the technology of OpenGL and the implementing method are particularly discribed. The contrast analysis of the effect images indicates that the three dimensional images constructed by the method have some ascendant features, such as favorable third dimension, quick calculation rate and strong mutual performance.
