Point-based Rendering of Water Surfaces with Splashes Simulated by Particle-based Simulation

Abstract

In recent years, attention has been paid to particle-based fluid simulation, and many rendering methods for the results of the particle-based fluid simulation have been proposed. We propose an efficient rendering method for the results of the particle based fluid simulation taking into account splashes. We calculate the water surfaces and the surfaces of the splashes by assigning the density to each particle and extracting isosurfaces. The surfaces of the water and splashes are then sampled by points. This makes it possible to render the changes of the shapes from the water surface to splashes efficiently by using the point-based rendering.
