Experiments have been implemented on a common PC with standard graphics hardware.

Finally, various ocean waves under different distance and different viewpoints are realistically view-dependent rendered. The 'border slit' on screen can be removed by the method based on 'Clamp Sphere'. This yields real-time performances, even when the camera moves. Then, relying on a procedural ocean wave model, the method restricts computations to the visible part of the ocean surface with screen-subdivision algorithm, adapts the geometric resolution to the viewing distance: high resolution in near area and low resolution in far area. It reduces the computation obviously and resolves the 'compress phenomenon' at high latitude. First, considering the effect of earth curvature in detail, the authors set up the ocean wave model based on digital earth and the knowledge of ocean. In this paper, considering earth curvature, an efficient view-dependent modeling and rendering method of large-scale ocean wave is presented. Summary The realistic modeling and rendering of ocean surface is one of hotspot and difficult problem of computer graphic. The system for modeling and animating the interaction between realistic-looking water and a computer graphics environment described in this article, draws on the science of computational fluid dynamics to calculate an approximate velocity field describing the time-varying motion of a volume of water. A pragmatic approach to the problem of water simulation is described in this article.

Mechanical engineers and physicists have been modeling the behavior of liquids on computers for nearly 40 years. Modeling physics on a computer and visualizing the results using graphics techniques can lead to complex pictures as dazzling as the real-world phenomena they are intended to represent, especially for such fluid effects as the motion of water, fire, and smoke. The reasons for wanting greater physical realism vary depending on the application. An ongoing goal for computer graphics is to provide tools not only for the artistic rendition of our physical world but for re-creating as much of our world in as realistic a way as possible. The article focuses on cognitive modeling for games and animation The article focuses on modeling water for computer animation.
