Particle simulation is a powerful method to study the dynamic behavior of fluids. In this method, fluids are modeled as systems of small particles with the proper physical properties. Large-scale 3D point data are often obtained as a result of particle simulations. In this paper, we visualize the data using particle-based rendering, which we recently proposed. The idea is to utilize the 3D points directly as the rendering primitives, which we call ”particles”. Based on this scheme, we can generate quick and high-quality visualization of large-scale particle simulations. Moreover, we can easily fuse objects surrounding or underlying the simulated fluid. It is also possible to fuse multiple physical values, for example, the velocity and vorticity of the simulated fluid. We demonstrate our method by applying it to a large-scale tsunami run-up simulation for the Great East Japan Earthquake, which occurred in March 2011.
