Interactive Flow Visualization Using Haptics

该项目将用局部可视化方法扩展全球视觉显示技术，将图形与触觉（力反馈）显示结合在三个领域：1。允许用户在全局可视化显示（通过线积分卷积（LIC），体绘制或特征提取创建）中应用众所周知的局部技术（例如流线或释放有色染料）。开发触觉界面，以补充表示矢量场的局部视觉方法。这些界面将被测试并相互比较，并使用可视化的方法。将触觉和视觉算法集成到计算转向环境中。这将允许在改变可视化参数时快速反馈，例如3D的位置，流线平流部件或触觉交互方法。该项目将使用一个共同注册的半沉浸式环境，由一个fake espace沉浸式工作台和一个大型SenseAble Phantom 3.0触觉设备组成；其他触觉设备可能会在稍后添加。通过在半沉浸式工作空间中共同注册触觉，用户将能够看到和感受到正在研究的领域。

This project will extend global visual display techniques with local visualizationmethods, which combine graphics with haptic (force feedback) displays in three areas:1. Allow users to apply well-known local techniques (e.g. streamlines or releasing colored dyes) within a globally visualized display (created by line integral convolution (LIC), volume rendering, or feature extraction).2. Develop haptic interfaces to complement the local visual methods for representing vector fields. These interfaces will be tested and compared with each other and with visual methods.3. Integrate haptic and visual algorithms into a computational steering environment. This will allow for fast feedback upon changing visualization parameters, such as the location of a 3D, stream line advection widget or the method of haptic interaction.The project will use a co-registered, semi-immersive environment consisting of a Fakespace Immersive Workbench and a large SenseAble Phantom 3.0 haptic device; other haptic devices may be added later. By co-registering haptics in the semi-immersive workspace, the user will have the ability to both see and feel the field under study.
