虚拟现实环境中涡流特征的多通道感知技术研究

Multimode Perceptual for Vortex Feature on Virtual Reality Environment

科学计算可视化给工程师提供一个洞察产品性能的有效途径。然而传统的可视化技术几乎都在视觉上传递信息,多元显示、全局视角、交互等都约束了对产品更深一步的观察。本文提出了一种结合涡流特征提取、涡流基于特征的可视化、涡流特征的声音表达得多通道感知技术,对三维矢量场的多维数据更深一步探测。结合虚拟现实技术,提供用户栩栩如生、身临其境、高交互的多通道感知矢量场的环境。

Computational fluid dynamics is becoming increasingly important for evaluation of design concepts in theproduct development process. Scientific visualization provides a very efficient way to insight into the performance ofproducts. Computational scientists need sophisticated tools to analyze complex data sets and view the results of large-scale numerical simulations. In this paper we present a new method for combining the vision, auralization and haptic of the vortices of a streamline in a vector field. This paper emphasizes the multimode, which sounds mapping and haptic mapping, including vertical feature extraction, vortex feature visualization, vortex sonification and haptic visualization of vortex. We are developing a visualization tool, which incorporates virtual reality techniques of the interactive exploration of the large scalar and vector data sets.
