When a particle-based volume rendering is applied to a volume dataset, a huge number of particles may be generated if some transfer function is specified. It is pointed out that there is a possibility that the decrease of the frame rate may hamper an effective remote collaboration work. In this research we propose a technique for decreasing the number of particles by modifying the transfer function so that the feature of the transfer function can be kept and enlarging the radius of the particles and confirmed their effectiveness. In addition, we developed a middleware to divide a given volume dataset on the data server for the efficient data communication and confirmed its effectiveness.
