中文摘要：
分析了三维数据场可视化的典型应用及两类基本构造方法；提出一种椭球体三维数据场可视化模型，详细论述该模型的物理意义及实现算法，并给出利用该模型及其算法实现三维数据场可视化的实例。通过对效果图的分析表明，该方法所建立的三维图像具有良好的真实感，运行速度快且交互性能强。
英文摘要：
The typical application of 3-D data field visualization and its two basic constituting methods are analyzed. An ellipsoid 3-D data field visualization model is proposed, the physical meaning and implementing algorithm of this model are discussed. An example of application of the model and algorithm to implement 3-D data field visualization is given. The contrast analysis of the effect images indicates that the 3-D images constructed by the method have some ascendant features, such as favorable 3-D, quick calculation rate and strong interactive performance.
