Abstract
An immersive type virtual reality (VR) system has been used as one of the visualization techniques for analyzing various complicated phenomena in a computational science. On the other hand, the volume rendering method is widely used for the intuitively understanding of 3-dimensionaly distributed physical quantities. Thus, it is very useful to apply the volume rendering method to the immersive VR system. However, a plane slice sampling method conventionally used in the volume rendering method has a problem that the quality of visualized images deteriorates in the immersive VR system. In this research and development, a sphere slice sampling method is applied to resolve this problem. In this presentation, the comparison between these two methods about the quality of image and the display speed has been performed. Further, the comparison between the hardware volume rendering method and software volume rendering method has been performed.
