Virtual Reality Visualization by CAVE with VFIVE and VTK
  The CAVE-type virtual reality (VR) system was introduced for scientific visualization of large scale data in the plasma simulation community about a decade ago. Since then, we have been developing a VR visualization software, VFIVE, for general CAVE systems. Recently, we have integrated an open source visualization library, the Visualization Toolkit (VTK), into VFIVE. Various visualization methods of VTK can be incorporated and used interactively in VFIVE.
