SPH-Based Fluid Simulation for Special Effects
Simulating natural phenomena like smoke, sand or fluid by physics-based algorithms is a very complex and important task in the visual effects industry. Animating fluids is time-consuming and the result is hard to control. There are only a few commercial fluid simulators on the market, which fit the high expectations of the effect artists. Our goal is to develop a physically correct fluid simula...
متن کاملCreating and Preserving Vortical Details in SPH Fluid
We present a new method to create and preserve the turbulent details generated around moving objects in SPH fluid. In our approach, a high-resolution overlapping grid is bounded to each object and translates with the object. The turbulence formation is modeled by resolving the local flow around objects using a hybrid SPH-FLIP method. Then these vortical details are carried on SPH particles flow...
متن کاملReal-time fluid simulation with adaptive SPH
We present a new adaptive model for real-time fluid simulation based on Smoothed Particle Hydrodynamics (SPH) framework. Unlike traditional time-consuming SPH methods, our model can simulate fluid at a considerably faster speed without losing realism. In our model, we first introduce the non-uniform particle system and propose a generalized distance field function which considers not only geome...
متن کاملParallel-optimizing SPH fluid simulation for realistic VR environments
In virtual environments, real-time simulation and rendering of dynamic fluids have always been the pursuit for virtual reality research. In this paper, we present a real-time framework for realistic fluid simulation and rendering on graphics processing unit. Because of the high demand for interactive fluids with larger particle set, the computational need is becoming higher. The proposed framew...
متن کاملSPH Based Shallow Water Simulation
We present an efficient method that uses particles to solve the 2D shallow water equations. These equations describe the dynamics of a body of water represented by a height field. Instead of storing the surface heights using uniform grid cells, we discretize the fluid with 2D SPH particles and compute the height according to the density at each particle location. The particle discretization off...
