Simulation Of Pouring Out Fluid Based On SPH

With the rapid development of computer hardware and its peripheral equipment, how to realistic simulation the natural landscape become a most challenging area of research directions in graphics. So for, animated fluids can add substantial realism to interactive applications such as surgery simulators or computer games. And then all kinds of chemical regent can simulate by fluid simulator technology in chemical experiments simulation. In this paper I propose SPH(Smoothed Particle Hydrodynamics)method to modeling chemical regent. This method is an extension of the Particle-Based Fluid Simulation by Matthias Muller which deriving the force density fields directly from the Navier-Stokes equation and by adding a term to model surface tension effects. In contrast to Eulerian grid-based approaches, the particle-based approach makes mass conservation equations and convection terms dispensable which reduces the complexity of the simulation. And I propose Marching Cubes algorithm to create the surface of fluids. Marching Cubes is a method to construction the surface of 3D objects, which is used to models of constant density surfaces from 3D medical data in medical imaging, and used in many fields. In Laboratory Chemistry simulation, we use SPH to modeling the motion of the fluids and use Marching Cubes to construction the surface of fluids. So we can realize modeling chemical regent with different density, viscosity and color. And then our animation method is fast enough to be used in interactive systems and to allow for user interaction with models consisting of up to 10000 particles.
