Three-dimensional fluid simulation method based on graphic processing unit (GPU)

Abstract

The invention provides a three-dimensional fluid simulation method based on a graphic processing unit (GPU). The method comprises the following steps of: acquiring and storing data information of a three-dimensional fluid to acquire the data information of the three-dimensional fluid; pre-processing the acquired data information of the three-dimensional fluid by the GPU to acquire a pre-processing result, and performing fluid simulation on the acquired data information of the three-dimensional fluid by the GPU to acquire a fluid simulation result of the data information of the three-dimensional fluid; and rendering the acquired fluid simulation result of the data information of the three-dimensional fluid to acquire a rendered fluid simulation result of the data information of the three-dimensional fluid. By the method, simple and real-time operation of the three-dimensional fluid simulation process can be realized.

Description

technical field [0001] The invention relates to the field of computer graphics, in particular to a GPU-based three-dimensional fluid simulation method. Background technique [0002] Fluid simulation is a very important technology in computer graphics and animation, and realistic fluid will bring users a more realistic experience. However, the simulation of fluids is difficult because correctly simulating fluid behavior, including the simulation of convection, diffusion, turbulence, and surface tension, is complex. [0003] There are usually two methods for fluid simulation: grid-based fluid simulation method and particle-based fluid simulation method. [0004] The grid-based fluid simulation method and the particle-based fluid simulation method are introduced in detail below. [0005] 1) The network-based fluid simulation method is to regard the fluid as continuous, discretize the spatial region into grids, and then use the finite difference method, that is, the Euler mode...

AI Technical Summary

Problems solved by technology

[0007] The disadvantage of the grid-based fluid simulation method is that the simulation process of convection, diffusion, turbulence and surface tension requires a large calculation intensity, and the entire simulation process cannot realistically simulate such as the simulation space. Bounded for some simulation effects

The advantage of this method is that it is simple and easy to implement; the disadvantage is that it is very inefficient
