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...
