Our research interest is to implement volume rendering on immersive projection technology (CAVE) at enough frame rate. It can be implemented on CAVE easily using texture mapping but there are some defects; for example the frame rate declines when the view point is close to the data and images projected to the screens become big. The reason seems that more than hundred images are enlarged and blended. Thus we try to find another way to implement it on CAVE. Considering that our graphic workstation (Onyx300) for CAVE is a parallel computer and there are some algorisms for volume rendering which improve the frame rate, we make the program that draws stereo images through two of the algorisms by parallel computing and displays only two images on CAVE. And we confirm that this program works well and draws stereo images at the sufficient frame rates. Finally we introduce the visualization of the void fraction of boiling flow measured by high-frame-rate neutron tomography by volume rendering on CAVE as an example of the application of this research.
