Animation Simulation Of 3D Water Based On Physical Model

In recent years, simulating natural phenomena has always been one of the most challenging tasks in computer graphics. Because natural phenomena is more complex than artifact, and the physical model of natural phenomena is more complexity. Simulating natural phenomena, such as hills, water, could, smoke, fire and so on, has been widely used in computer game, movie production, and advertisement, etc.But simulating water is more difficult, the reasons are: (1) the water is extremely irregular, and complexity and randomness; (2) the moving of water is complexes, which has to meet certain conditions. And in the process of moving, it is affected by many forces; (3) most of the physical models for water are partial differential equations. It is more difficult to solve. Stable Fluid is a method to solve Navier-Stokes equation for the approximate solution. The method was satisfied with the stability of vision, while the approximate solution must satisfy the real-time. Water model also meets the Navier-Stokes equations. The method of Stable Fluid is used to simulate for water.In this paper, we compare the methods for water simulation; on this basis we introduce the shallow water wave equation - Navier-Stokes equation, and its solution. Through the establishment of physical model, we automatically complete the water simulation. The experimental results show that water movement is realistic, and the successful simulation of the wave reflection, refraction phenomenon and superimposed.The former two chapters introduce challenges of the thesis and methods of simulating water. After The third chapter, we introduce the method to resolution function. Last we get the answer and the result of experimentation.
