Abstract

In this paper, we present a framework for real-time and realistic rendering of large-scale deep ocean surface, which uses LOD scheme and height map to model water surface on CPU and takes full advantage of GPU for vertex and pixel processing. We present multi-resolution nested regular grids, as a LOD scheme, to support free and real-time navigation on large-scale sea area. Previous work neglected the wind changing effect on ocean waves, here we propose a wind model to improve the existing method of ocean wave gen-eration and satisfy the requirement of realistic simulation with wind effect. Experiment results show that our approach is efficient and can achieve interactive rates for the simulation of large-scale deep ocean surface.
