Research On 3D Ocean Scene Simulation Technology

The simulation of 3D ocean scene is one of the research contents of computer graphics scene modeling.The difference between ocean scenes and other natural scenes is that ocean scenes are often random,which is difficult to simulate.At present,there is no detailed division for the sea surface illumination simulation in the simulation scene of the ocean scene,only a simple illumination model is used for rendering,and the analysis of floating objects on the sea surface in the scene is not comprehensive enough.In this paper,a complete 3D ocean scene will be realized.For the illumination rendering of the sea surface,the rendering of the above and below the sea surface will be integrated to simulate the effect of light in the ocean scene more really.Besides,the floating objects on the sea will be simulated and the force of the objects will be analyzed by multiple factors.The main research contents and results of this paper are as follows:Firstly,mainstream wave modeling methods were used to conduct research and experimental simulation respectively,and the results were analyzed and compared.The three modeling methods based on geometric model,physical model and wave spectrum model are compared respectively from the aspects of the authenticity,real-time performance and algorithm complexity of the simulated scene to select the appropriate simulation method.Secondly,the Unity 3D engine is used to build and render a complete three-dimensional ocean scene,including terrain,vegetation,ocean and other object models.In view of the illumination and rendering of the scene model,the reflected light on the sea and the scattered light on the next surface of the sea are integrated to achieve the rendering of the whole scene of the sea.Finally,the interaction behavior between the water surface and the object in the ocean scene is simulated.For the floating objects on the sea surface,the movement of the objects under the action of forces is simulated by analyzing the forces from many aspects.For the spray and foam generated by the virtual sea surface,the particle system and texture mapping technology are used to draw and simulate.
