“…Although these methods can generate high quality results of water wave simulation, therefore all of these methods are computationally expensive, can not simulating large area of nearshore wave.

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.

“…Longo et al [14] gave a review for turbulence in the swash zone and discussed the measurement techniques and generation of breaking waves. There also have shallow-water simulations using a depthintegrated [15], spectrum [16,17], 2D Boussinesq equations [18], video-based method [19], and so forth. The geometry based methods are suitable for large-scale real-time water because of simple computation.…”

We introduce an automatic optimization approach for the simulation of large-scale coastal water. To solve the singular problem of water waves obtained with the traditional model, a hybrid deep-shallow-water model is estimated by using an automatic coupling algorithm. It can handle arbitrary water depth and different underwater terrain. As a certain feature of coastal terrain, coastline is detected with the collision detection technology. Then, unnecessary water grid cells are simplified by the automatic simplification algorithm according to the depth. Finally, the model is calculated on Central Processing Unit (CPU) and the simulation is implemented on Graphics Processing Unit (GPU). We show the effectiveness of our method with various results which achieve real-time rendering on consumer-level computer.
