“…The challenge at hand is to simulate and render large-scale ocean surfaces while maintaining a balance between efficiency and quality on power-limited platforms like web and mobile devices. Existing industrial solutions for addressing ocean surface rendering issues primarily involve techniques such as Fast Fourier Transform (FFT) for wave simulation [3], which relies on bandwidth and general-purpose computing, Gerstner wave stacking technology [4], which is constrained by iteration times, and the method of bump mapping [5], which often lacks rendering details.…”

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.
