Abstract

The application provides a general-purpose-graphics-processing-unit (GPGPU)-rendering-based simulation method and simulation system for 3D sea water. The simulation method comprises: a CPU is used for initialization and an ocean-surface grid is generated dynamically; parallel computing is carried out on the ocean-surface grid by using the GPGPU; and the GPGPU executes a 3D Kochin algorithm to obtain a marine navigation track of a ship and calculates a mixing effect of sea water and a coastline. According to the method provided by the application, all computing and rendering are arranged in the GPGPU and sea water module computing and rendering form an integrated flow in the GPGPU, thereby reducing communication between an internal memory and a video memory and thus realizing the GPGPU performances fully and improving the simulation efficiency. On the basis of the method, rendering, reflecting, and refraction of sea water and waves as well as good coordination of the visual effect reality sense of the ship track and simulation real-time performance are realized.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a 3D seawater simulation method and simulation system based on GPGPU rendering. Background technique [0002] Seawater simulation is now a difficult problem displayed on the graphics card, because of its reflection, refraction, shape changes, etc., making the simulation of seawater very difficult. In the existing technology, the degree of simulation in seawater simulation is not high enough to realize real-time simulation in large areas, the degree of simulation of wave fluctuations in ocean waves is relatively low, and the operating efficiency is low. Due to the unsatisfactory simulation algorithm, there is no obvious wave effect when the ship sails at sea, or the wave effect is realized through special effects, and the sense of simulation is relatively weak. The ripple effect on the sea surface similar to that of a helicopter suspended in the sea has not been realized....
