Advanced display technologies have made the virtual exploration of relatively complex models feasible in many applications. Unfortunately, only a few human interfaces allow natural interaction with the environment. Moreover, in surgical applications, such realistic interaction requires real-time rendering of volumetric data-placing an overwhelming performance burden on the system. We report on a collaboration of an interdisciplinary group developing a virtual reality system that provides intuitive interaction with volume data by employing real-time volume rendering and force feedback (haptic) sensations. We describe our rendering methods and the haptic devices and explain its utility of this system in the real-world application of Endoscopic Sinus Surgery (ESS) simulation.
先进的显示技术使在许多应用中对相对复杂的模型进行虚拟探索成为可能。不幸的是，只有少数人机界面允许与环境进行自然交互。此外，在外科手术应用中，这种逼真的交互需要对体数据进行实时渲染，这给系统带来了巨大的性能负担。我们报告了一个跨学科团队的合作，该团队正在开发一种虚拟现实系统，该系统通过采用实时体渲染和力反馈（触觉）感觉来提供与体数据的直观交互。我们描述了我们的渲染方法和触觉设备，并解释了该系统在内窥镜鼻窦手术（ESS）模拟的实际应用中的效用。
