A Multimodal Virtual Reality Interface for VTK
نویسندگان
چکیده
The object oriented Visualization Toolkit (VTK) is widely used for scientific visualization. VTK is a visualization library that provides functions for presenting 3D data. Interaction with the visualized data is done by mouse and keyboard. Support for three-dimensional and multimodal input is non-existent. This paper describes VR-VTK: a multimodal interface to VTK on a desktop virtual environment. Six degree of freedom input devices are used for spatial 3D interaction. Head tracking is used for camera control. Pedals for clutching. Speech input is used for application commands and system control. To address several problems specific for spatial 3D interaction, a number additional features, such as more complex interaction methods and enhanced depth perception are discussed. Furthermore, the need for multimodal input to support interaction with the visualization is shown. An existing VTK application is ported to VR-VTK. Informal user experiences are presented.

متن کاملUsing a Virtual Reality Environment to Simulate the Pushing of Cylindrical Nanoparticles
With the rise in the use of AFM (Atomic Force Microscope), we have witnessed a growing use of atomic microscope based nanorobots in the precise displacement of various particles. There are certain limitations to the application of nanorobots in the moving of nanoparticles. One of the most important of these limitations is the lack of an appropriate image feedback concurrent with the displaci...

vjVTK is a small toolkit enabling the use of the Visualization ToolKit (VTK) natively within the VRJuggler Virtual Reality framework. The toolkit enables a departure from the traditional visualization calculation-conversionimmersive viewing cycle. vjVTK leverages the OpenGL capabilities of VTK to allow it to run as a native graphics generation tool within the VRJuggler framework. This removes t...
