中文摘要：

三维流场可视化主要通过计算机图形学方法来描述复杂的流场结构,揭示流体内部规律和物理特征,在航空、气象、医学等领域具有重要意义。由于三维空间维度和数据量的影响,目前三维流场可视化中尚存在不少问题亟待解决。对三维流场可视化研究现状和方法进行了分类描述,从基于线的可视化、基于面的可视化、基于体绘制的可视化以及基于纹理的可视化等4个方面对当前的研究现状加以分析总结,介绍了各方面的研究进展和存在的问题。总结了三维流场可视化中的主要问题,并对未来工作提出了一些建议。

英文摘要：

3D flow visualization describes the complex flow structure by computer graphics methods, reveals the internal laws and physical characteristics of the fluid, and has an important role in the aviation, atmosphere, and medicine and so on. There are many problems to be solved in the 3D flow visualization because of the dimension and the data scale of the 3D space. The classification of the 3D flow visualization was showed by the research status and methods, which could be divided the line-based visualization, surface-based visualization, volume rendering and texture-based visualization. The progress and problems in the above aspects were analyzed. Some main problems in 3D flow visualization were showed and some advice for future work was provided.
