A function to extract ROI (region of interest) with automatic LOD (level of detail) is incorporated to VFIVE, which is an interactive visualization software for the CAVE system, to visualize large scale data generated by computer simulations. The ROI extraction can be carried out interactively and intuitively in the CAVE system, and is recursive. The resolution of data for isosurface and volume rendering are always constant regardless of the size of the ROI. The processing time for visualization and the frame rate are kept roughly constant. The VFIVE with this function was used to visualize large scale data interactively in the CAVE system, and it worked successfully.
