AI Technical Summary

Technical Problem

Traditional ocean flow field visualization methods lack the ability to express three-dimensional details of the sea surface, have a single visual effect, discontinuous texture, and high computational overhead. They are unable to meet real-time requirements and have difficulty capturing the dynamic characteristics of multiple wave components.

Method used

The Gerstner wave model is used to calculate the superposition textures of multiple groups of waves offline. The local deformation is analyzed by the Jacobian matrix. Combined with the multi-phase dynamic sampling strategy, high-precision wave textures are generated and weighted mixing is performed to achieve the continuity and realism of the flow field data.

Benefits of technology

It improves the realism and continuity of ocean flow field visualization, reduces computational overhead, achieves a smooth interactive experience at high frame rates, and enhances the details and dynamic performance of sea surface morphology.
