Problems solved by technology

[0006] The existing technology only uses wind to calculate the one-dimensional wave spectrum, ignoring the influence of other factors such as ocean currents, and cannot truly reflect the wave environment. The conversion of the wave spectrum does not take into account other interference and changes that will occur during the conversion process, only c

Abstract

The invention relates to a three-dimensional ocean wave simulation optimization method for dynamic positioning ship offshore operation. Firstly, the terrain blocks are triangulated to form triangularmeshes to construct sea level. Then, considering the main action and influence factors of ocean waves-wind, current and so on, the height map is generated based on Fast Fourier Transform (FFT), and then the height field is calculated and simulated to generate ocean waves. Then the GPU and CPU are used to speed up the parallel computing. Finally, the Vega Prime visual development platform is used to simulate and show the wave simulation results. The optimized simulation method can model and render ocean waves scientifically, realistically and realistically, realizes real-time 3D ocean wave scene simulation, and increases the real-time and interaction of ocean waves to a certain extent.

Description

technical field [0001] The invention belongs to the field of three-dimensional visual simulation of ocean scenes, in particular to a three-dimensional ocean wave simulation optimization method for dynamic positioning ships operating at sea. Background technique [0002] Dynamically positioned ships have the advantages of strong adaptability, no limitation of water depth, accurate positioning, and convenient operation, so they occupy an important position in actual ocean engineering applications. Ocean waves are a very complex fluctuation phenomenon generated on the surface of the ocean due to the action of wind and current, which are closely related to our economic and social activities. Due to the constraints of the natural environment and complex and changeable factors, if we can simulate the three-dimensional wave scene of the dynamic positioning ship's offshore operation in real time and realistically, it will be of great significance for the application of marine engine...
