Tutorial introduction to Virtual Reality: What possibility are offered   to our field?
  The virtual reality (VR) provides us a three-dimensional, immersive, and fully interactive visualization environment. To make the best use of the VR's potential in scientific visualization, a VR visualization software named VFIVE has been developed for the CAVE-type VR system. VFIVE enables simulation researchers to analyze three-dimensional scalar and vector fields by various visualization methods including real time volume rendering in the CAVE's room sized booth. Some basic visualization tools of VTK have been integrated to VFIVE, too.
