Visual Simulation of Water Using Overlapping Grids

Abstract

In recent years computer graphics have been used in many applications such as movies and computer games and the visual simulation of natural phenomena has become an important research topic. Especially, many researchers have paid attentions to the simulation of the natural phenomena related to fluids such as water, smoke and flame. In the traditional methods, a single grid was used for computing the fluid motion. However, it is necessary to increase the number of grid points in order to increase the accuracy, and this results in the high computational cost. The computational cost is further increased when objects with complicated shapes interact with the fluids. To address this problem, a method using overlapping grids has been proposed. In this paper, we propose a new method for the visual simulation of the water using the overlapping grids. Our method is very efficient and suitable for simulating the interaction of objects and water.
