我们描述了加权距离变换（WDT）的使用，以增强为分割解剖数据集的体可视化而设计的应用程序。加权距离变换被作为一种生成标量场派生特征的通用技术提出，该特征在渲染过程中可通过多种方式使用。我们通过在图形卡上计算加权距离变换来实现与体数据的实时交互。详细介绍了该技术应用于解剖结构教学应用程序的几个示例，包括渲染嵌入结构、模糊边界、勾勒轮廓以及间接光照估计。
We describe the use of the weighted distance transform (WDT) to enhance applications designed for volume visualization of segmented anatomical datasets. The WDT is presented as a general technique to generate a derived characteristic of a scalar field that can be used in multiple ways during rendering. We obtain real-time interaction with the volume by calculating the WDT on the graphics card. Several examples of this technique as it applies to an application for teaching anatomical structures are detailed, including rendering embedded structures, fuzzy boundaries, outlining, and indirect lighting estimation.
