摘　　要：体可视化是一门交互地视觉呈现三维数据场的技术,允许用户直观方便地理解数据中所包含的几何结构和特征信息,在医学影像、石油勘探、大气气象和科学计算模拟等领域得到广泛应用.由于三维数据场内部特征的复杂性,实现高表达力的体可视化需要同时考虑数据的特性和用户的因素.基于感知的体可视化技术在可视化流程中考虑人类感知过程和认知过程的特点,使得可视化的结果符合人类感知特性和习惯,达到有效地揭示数据特征的目的.文中从用户驱动的体数据分析、符合感知的可视化设计和表意性体可视化3个方面对基于感知的体可视化的相关技术进行梳理总结,并指出该领域需要进一步探索的研究方向.Volume visualization seeks to visually display 3D data field to allow users effectively explore the hidden geometric structures and features. It has been widely applied in many fields, like medical imaging, oil exploration, atmosphere and meteorology, scientific computing and simulation. Because of the complexities of the internal features in 3D data fields, both the data characteristics and the users should be considered to achieve highly expressive volume visualization. Perception-based volume visualization sufficiently integrates the characteristic of the perceptual and cognitional processing of human beings into the visualization pipeline, and is capable of better revealing the features. In this paper, we summarize related work on perception-based volume visualization including user-driven volume data analysis, perception-based visual design, and illustrative volume visualization. We also discuss future work of this research topic.
