“…Pre-rendering methods [12,13] involve the prior calculation and storage of water surface wave information, commonly employed in applications requiring high realism. Statistical model methods [14,15], based on FFT, find widespread use in the film and video game industries [16] due to their exceptional realism and global controllability.…”

The real-time simulation technology of large-scale open sea surfaces has been of great importance in fields such as computer graphics, ocean engineering, and national security. However, existing technologies typically have performance requirements or platform limitations, and the two are often impossible to balance. Based on the camera-view-based screen space level of detail strategy and virtual camera pose adaptive filtering strategy proposed in this article, we have developed a fast and comprehensive solution for rendering large-scale open sea surfaces. This solution is designed to work without the need for special hardware extensions, making it easy to deploy across various platforms. Additionally, it enhances the degrees of freedom of virtual camera movement. After conducting performance tests under various camera poses, our filtering strategy was found to be effective. Notably, the time cost of simulation using 60 waves at the height of 6 m above sea level was only 0.184 ms. In addition, we conducted comparative experiments with four state-of-the-art algorithms currently in use, and our solution outperformed the others with the best performance and suboptimal visual effects. These results demonstrate the superiority of our approach in terms of both efficiency and effectiveness.

“…Reference [1] given its own modeling method to real-time rendering of a wide range of ocean surface and certain effect has been achieved. Combining the actual observation data and the geometric wave theory together, the modeling method based on spectrum means that the actual waves are represented by a sum of the different amplitude and phase sine spectrums, using spectral analysis method to determine the characteristics of the composition of the wave spectrum [2]. The modeling method based on hydrodynamics theory can simulate the moving of the internal particles of the ocean by solving the dynamics equation, rather than simulate of the movement of wave on ocean surface directly.…”

Mild-slope equation is usually used in many simulation applications. The equation has obviously benefit which based on physical method that can present the real status of water, but the shortcoming is also clearly that the calculations spending lots of times which not support some real-time applications. We use hyperbola to simple the equation calculation process, and use alternating directions implicit (ADI) way to solve this equation. The result shows that the ADI way can use less calculation and less time to accomplish the calculation. We also use the new features of GPU(graphics process unit) to speed up the calculation so that we can render the surface in real-time application.

“…Lee et al [LBR07] combine a superposition of sinusoids and the TMA spectrum (Texel, Marson and Arsole, based on Jonswap's) [BGRV85], creating a better statistical distribution of waves. It also offers better control for the end-user who can change parameters such as the bottom depth, thus enabling him to generate different types of water volumes (lakes, rivers, etc).…”

International audienceThis paper presents a survey of ocean simulation and rendering methods in computer graphics. To model and animate the ocean's surface, these methods mainly rely on two main approaches: on the one hand, those which approximate ocean dynamics with parametric, spectral or hybrid models and use empirical laws from oceanographic research. We will see that this type of methods essentially allows the simulation of ocean scenes in the deep water domain, without breaking waves. On the other hand, physically-based methods use Navier-Stokes Equations (NSE) to represent breaking waves and more generally ocean surface near the shore. We also describe ocean rendering methods in computer graphics, with a special interest in the simulation of phenomena such as foam and spray, and light's interaction with the ocean surface
