Fast Simulation Of Large-Scale Water Surface Interacting With Objects

In recent years, with the strengthening of GPU processing power, the physical effect of rendering computer graphics-based applications become mainstream, for higher complexity and real-time requirements of applications such as high complexity water scene in the game, today's consumer-level graphics card calculation process can't be achieved purely physical models of real-time application requirements, the study of complex water fast interactive simulation is still necessary.This paper presents a novel method of spherical projected grid approach, use the FFT simulation resulting in water surface in an open environment, the use shifting water grid to achieve simulate the large-scale water surface to the rigid body dynamics coupling, we introduced the fast GPU implementation, which is adaptive to render water wave effects around the vessel, the PML methods is to ensure the continued stability of the shifting grid boundary waves.In addition, this paper presents a simplified method to improve the rigid body dynamics, showing the water surface fast simulation with rigid body interaction. Many engines use a three-dimensional grid scenarios are based on the terrain, the least efficient algorithm blindly execute a series of time-consuming segment polygon intersection tests proposed, in this paper based on the quadTree, using point sweep algorithm detects possible collisions Tile since collision detection include only a few floating-point comparison, therefore a smaller amount of calculation. Low accuracy in the test case, the method of dynamic collision checking has a good effect. This paper also presents a combination of shallow water equations twisted surface rendering method. Finally shore wave attenuation reflection, realized coloring and rendering a complete real-time bubble coastline. Experimental results show that this scheme can achieve high performance and realistic effects, suitable for real-time environments, such as computer games.
