Abstract-Direct volume rendered images (DVRIs) have been widely used to reveal structures in volumetric data. However, DVRIs generated by many volume visualization techniques can only partially satisfy users' demands. In this paper, we propose a framework for editing DVRIs, which can also be used for interactive transfer function (TF) design. Our approach allows users to fuse multiple features in distinct DVRIs into a comprehensive one, to blend two DVRIs, and/or to delete features in a DVRI. We further present how these editing operations can generate smooth animations for focus + context visualization. Experimental results on some real volumetric data demonstrate the effectiveness of our method.
摘要——直接体绘制图像（DVRIs）已被广泛用于揭示体数据中的结构。然而，许多体可视化技术生成的DVRIs只能部分满足用户需求。在本文中，我们提出了一个用于编辑DVRIs的框架，该框架也可用于交互式传递函数（TF）设计。我们的方法允许用户将不同DVRIs中的多个特征融合成一个综合特征，融合两个DVRIs，和/或删除DVRIs中的特征。我们进一步展示了这些编辑操作如何为聚焦+上下文可视化生成平滑动画。在一些真实体数据上的实验结果证明了我们方法的有效性。
