This paper presents a new method to simulate large areas of near-shore waves. Firstly

the correct wave surface movement at appointed area in a period of time is obtained by solving Boussinesq type equations

which can describe the compositive phenomena of near-shore wave： refraction

diffraction

reflection and wave-wave interaction. Secondly

the movement of wave in finite time can be changed to infinite time by reconstructing the sequence of the waves height fields. Finally

in real-time rendering process the corresponding wave height fields are sampled by the view-dependent sea surface grid as vertex textures. The experimental results show that this method is realistic and effective. It is appropriate for real-time simulation applications.
