With the recent development of supercomputers, it is required to efficiently visualize the result of super-large scale numerical simulations on a few hundreds to a few ten thousands of parallel processes. Conventional offline-processing of visualization give rise to difficult challenges such as transferring large-scale data and reassembly of extensive amount of computational result files, which is inevitable for sort-first or sort-last visualization methods. On the other hand interactive use of a supercomputer is still limited. We propose a remote visualization system for solving these problems by applying Particle-based Volume Rendering which is sortless volume rendering technique and convert resulting data to rendering primitive particles. Proposed system can generate particles on same number of parallel processes of the numerical simulation and transfer the particles to a visualization server. Proposed system allows users can observe the resulting data with changing the camera position freely.
