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

Creating realistic animations of water is a challenging problem in the field of computer graphics. To create realistic animations of water, the fluid simulation of the movement of water is necessary. In recent years, attention has been paid to particle-based fluid simulation. Although several methods have been proposed to render the results of the particle-based simulation, there are few methods to render splashes. This paper presents an efficient rendering method for the results of the particle-based simulation with splashes. We calculate the water surfaces and the surfaces of the splashes by assigning the density to each particle and extracting iso-surfaces. The surfaces of the water and splashes are then sampled by points. This makes it possible to render the water surfaces and splashes efficiently by using point-based rendering.
