摘　　要：体可视化能够直观地展示体数据内部的特征信息,被广泛应用于医学影像、地质勘探、科学计算模拟等领域.高质量绘制体数据内部特征信息是用户理解和处理体数据的前提,传统的方法依赖于数据的高分辨率采样,并采用传输函数调节获得高质量的绘制效果.文中主要综述了基于特征增强的体可视化方法,以及对反映体数据特征信息空间关系的光照技术的研究现状,最后给出了这些方法的发展趋势及展望.Volume visualization is to present inner structures of volumetric datasets effectively, so it has been widely applied in medical imaging, geological exploration, scientific computing and simulation and so on. High quality rendered inner structures of the volumetric dataset is very important to understand the volumetric dataset. To achieve this aim, traditional methods rely on high-resolution samples of the dataset and a good transfer function. In this paper, we summarize visualization methods based on feature enhanced, and we introduce volume illumination which can explore the spatial relationships of features of the volumetric dataset. Finally, we discuss future work of those research topics.
