wave particle and its mirrors. Distribution of particle origins. (A) and (B) are the position of the wave particles and the radial wavefront shape they represent. In: Computer graphics forum. Particle-based fluid simulation for interactive applications. Thanks for your help! But in our method, the wind field is actually an artificial vector field. Deutches Hydrographisches Institut, 1973. Mitchell 11 implemented Tesserdorfs method on GPU by employing a low-frequency band to displace the geometry of the ocean surface and a broad band to represent fine ocean details with interactive frame rates. Following these authors, Tesserdorf 9 used the spectral components obtained from the Phillips spectrum 10 and a Gaussian pseudo-random generator to achieve a realistic result, and such approaches have become a classical method of ocean simulation. Thus, the distance, which is actually the wavelength of ocean waves i, between wave particles can be described as (17) The well-known dispersion relationship between wavelength and wave propagate speed is written as (18) The period of ocean waves T i, therefore, can be calculated. Leblanc Graham,. ATI ResearchTechnical Report, 2005, 121126. The physical process of the interaction between ocean surface and wind force is complex.
