And by applying the linear dispersion relation of wave, all the properties of wave refraction including wave rays, constant phase lines, phase function and crest lines etc., can be expressed in explicit functions. By introducing an orthogonal curvilinear coordinate along the wave ray and the constant phase line, and with an estimated scale factor, the refraction coefficients along any wave ray can then be determined. The present results are verified by ordinary wave ray theory and some previous numerical results.

When the viewpoint is changing quickly, the rendering algorithm ignores some details of the diffuse component, otherwise the scene is rendered more precisely. The Specula highlight is dependent of the viewpoint, it must be processed in real time. We present an algorithm to get rid of the area that does not contain specula highlight quickly and calculate only the area that contains the specula highlight. In order to calculate the specula reflection and refraction component, we presented a new raytracing algorithm based on the environment map transformation. The environment maps are constructed at the sample points of the scene in the preprocessing phase. We add depth information in the environment maps and generate the exact reflection and refraction intensity with the transformation of a few pixels.

对于表面光亮度漫射分量，由于它与视点无关，可以把面片按照光照细节的分布预剖分成层次结构，然后在实时漫游时根据场景变化的快慢决定绘制的细致程度；对于镜面高光分量，由于它与视点有关，必须实时处理，我们提出了一种快速高光裁剪算法，通过简单测试，去除那些不包含高光的区域，只处理包含高光的区域；对于镜面反射分量和折射分量，我们提出了一种基于环境映照变换的快速光线跟踪算法，预先在场景的离散采样点处建立环境映照，然后根据入射点的位置，把邻近采样点处的环境映照上相关象素处的可见点变换过来，求取反射分量和折射分量。

The results are verified from deep to extremely shallow water conditions. The shoaling waves, standing waves, 3D disturbance waves, tidal waves and solitude waves are simulated and verified,and waves over an underwater bar,the diffraction near single breakwater, breakwater gap, offshore breakwater, Breakhoff experiment are taken into account in this model. Furthermore, the wave harbor resonance under special topography, and "Bragg" resonance are simulated. The wave refraction problem under current fields,the nonlinear wave refraction-diffraction under "Arthur" current field, and the wave propagation under slowly varying current field are studied. The favorable calibrations show the model's feasibility in dealing with the wave nonlinearity and simulation in both deep and shallow water.
