| 摘 要： | INTRODUCTION Breaking wave is an interesting natural phe-nomenon. Many literary work including fiction, films and poems describe its beauty and pageantry. Fig.1 shows a wonderful scene of breaking wave.Breaking wave is also one of the most complex natural phenomena. It is still an open challenging Fig.1 A portrait of breaking waveproblem to produce realistic image of breaking wave in computer graphics. Breaking waves are tradition-ally modelled using sinusoidal and trochoidal func-tions…

| Abstract: | This paper proposes an approach for rendering breaking waves out of large-scale of particle-based simulation. Moving particle semi-implicit (MPS) is used to solve the governing equation, and 2D simulation is expanded to 3D representation by giving motion variation using fractional Brownian motion (fBm). The waterbody surface is reconstructed from the outlines of 2D simulation. The splashing effect is computed according to the properties of the particles. Realistic features of the wave are ren-dered on GPU, including the reflective and refractive effect and the effect of splash. Experiments showed that the proposed method can simulate large scale breaking waves efficiently. |
