In this paper, we propose a technique for visualizing volume datasets which are generated on memories of distributed computers using a PC-based volume rendering system. When we wish to monitor a on-going simulation on distributed computers, we often gather volume datasets on a graphics workstation and visualize an isosurface from these datasets. When the size of the generated isosurface is very large and is comparable to the size of the pixel, it requires much time to render them. To solve this problem, we choose a volume rendering method so that we do not use intermediate geometries such as isosurfaces. This approach is promising because a PC-based volume rendering board which can render a 2563 volume dataset at a rate of 30 frames per second has been commercialized recently. We will develop a system which monitors a large scale simulation by using the board as a voxel memory which distributed computers share.
