| Popis: | International audience; In Computer Graphics, existing ocean waves models still suffer from lack of realism and/or complexity of use essentially due to empirical definition of parameters by the user. In this paper, we propose an easy to use spectral ocean waves model whose parameters are obtained automatically from real world information. These parameters can be computed in two different ways. The first one makes use of measured oceanographic data and the second one is image based. Both are very fast and simple to use. By using real world information, we can achieve more realistic results than previous models. Ocean waves animation is very easy to perform with our spectral model. In addition, this model is procedural and allows a continuous representation of ocean surface away from shore with any size and any level of detail, while requiring very low memory storage. |
