Abstract

The invention provides a three-dimensional dynamic marine simulation method based on GPU (Graphics Processing Unit) multi-pass drawing. Vertex information is input at a time by means of an application program by using a plurality of GPU drawing channels, an OpenGL vertex buffer area object and a transform feedback technology, so that the calculation, iteration, assembly and rendering of a vertex are finished in a GPU. By adopting the method, the powerful parallel computing capability of the GPU is utilized fully, and the running efficiency and instantaneity of simulation programs are improved greatly on the premise of ensuring the effect of marine surface simulation.

Description

technical field [0001] The invention relates to a data processing method, in particular to a three-dimensional dynamic ocean simulation method based on GPU multi-pass rendering. Background technique [0002] In recent years, the simulation of realistic natural scenery has become a hot and difficult point in the field of computer graphics. It uses computer technology to seek mathematical models that can accurately describe various phenomena and landscapes in the objective world, and reproduce these phenomena and landscapes realistically. landscape. From a scientific point of view, the real-time modeling and rendering of realistic natural scenes is the difficulty, because many natural phenomena, including the above, are difficult to describe with accurate geometric models, which greatly increases the The difficulty of simulation. Among them, the simulation of ocean waves is the most complicated, mainly as follows: [0003] (1) The sea level is quite vast, and the shape of t...
