项目摘要

In this research, we developed a visualization system for physical values in virtual space by using virtual reality system as a visual method stimulating sensitivity of observers. The following systems and algorithms have been developed.(1) Development of visualization method of information distributed in 3D space by using virtual reality system : The best method to observe physical values distributed in 3D space is to utilize stereo system. We developed a virtual reality based visualization system which grasps the changes of the arbitrary 3D field distributions utilizing the movement of an object inside the 3D virtual space.(2) Developments of high speed algorithm and data structure for volume rendering : In order to observe vector values in 3D space, its magnitude, direction, loci, and also distributions in various states in 3D space should be displayed simultaneously. For realizing this, a new visualization method using streamlines and volume rendering technology together is developed.(3) Development of graphical user interface for virtual reality system : By using data grove and magnetic sensors, we developed graphical user interface using gestures going well human feelings.(4) Development high speed interpolation algorithm : We developed the interpolation algorithm that obtains the unknown physical value distribution at any positions bounded by two or more given analysis results where the moving object is placed discretely.

在本研究中，我们利用虚拟实境系统作为一种视觉化的方法，以刺激观察者的敏感度，发展出一个虚拟空间中物理量的视觉化系统。已经开发了以下系统和算法。(1)利用虚拟现实系统开发三维空间分布信息的可视化方法：观察三维空间分布的物理量的最佳方法是利用立体系统。我们开发了一个基于虚拟现实的可视化系统，该系统利用三维虚拟空间内物体的运动来掌握任意三维场分布的变化。(2)体绘制的高速算法和数据结构的发展：为了观察三维空间中的矢量值，需要同时显示其大小、方向、轨迹以及在三维空间中各种状态下的分布。为此，提出了一种将流线和体绘制技术相结合的可视化方法。(3)虚拟现实系统图形用户界面的开发：通过使用数据格罗夫和磁传感器，我们开发了图形用户界面，使用手势很好的人的感觉。(4)开发高速插值算法：开发了在离散放置移动对象的情况下，通过两个或多个给定分析结果得到任意位置处的未知物理量分布的插值算法。
