A new method for nearshore wave simulating is introduced. Firstly, parabolic mild-slope equations are set up according to the simulation area and input waves. After solving the equations, the integral wave parameters such as the root mean square wave height, the peak wave period and the mean wave direction can be calculated. Instantaneous surface elevations can also be obtained from the model. Then, the integral wave parameters and an instantaneous surface elevation are composed into a float texture. Finally, a viewpointdependent sea surface is rendered using this texture as wave parameters. Experimental results show that this method can be applied to simulate large area nearshore wave in real-time with realistic effect. It is suitable for the application of real-time simulation, particularly for marine simulator.

A novel method for simulating large-scale, nearshore sea surface is presented. The whole simulating process can be divided into two phases: pre-computing phase and real-time computing phase. In pre-computing phase, wave parameter distribution of a simulation area is worked out using the SWAN (Simulating WAves Nearshore) model on a coarse grid. In real-time computing phase, a small height field surrounding the viewpoint is generated using the Fast Fourier Transformation (FFT) based method every frame. The wave parameters used in the FFT-based method are dynamically changed according to viewpoint's projective position on the coarse grid. Then, the height field is saved as a vertex texture, which can be tiled in horizontal directions seamlessly. At last, the vertex texture is sampled by a sector sea surface, which is viewpoint-dependent and has Level Of Detail (LOD) effect. Several shading trips are used to generate optical effects of sea surface, such as reflection, refraction etc. Experimental results show this method can be applied to simulating large-scale sea surface in real-time with realistic effect. It is especially suitable for the application in maritime simulators.

Then they rendered the scene by using a particular illumination model and displacement mapping texture to deal with multi-wave trains.…”

The tsunami which happened in 2004 has made lots of damages, and people saw the video from TV, they finally know how terrible the tsunami is. However, the movements of tsunami waves are not like those which are shown in Hollywood movies. In ocean engineering, they only simulate the surface of the tsunami wave movements, and the simulations are not rendered in a realistic way. In computer graphics, the ocean simulations often show the results which focus on the small movement on the ocean surface. In this thesis, we want to combine advantages in these two domains. We hope that we can simulate the tsunami wave propagation by physically-correct equations developed in ocean engineering and we render the simulated scene by the techniques developed in computer graphics to make it realistic. And we hope that our simulation system can make people having more understanding about tsunami waves.
