    Abstract:

    Current simulation methods for large-scale complex water scenes suffer from various problems such as low efficiency, and complicated collision detection. To remedy these problems, this paper presents a novel method for ocean-scale complex simulation based on spherical mapping projected grid. First, a novel spherical projected grid method is proposed for animating large scale water waves. Compared with conventional projected grid method, the new method does not need reconstructing projectors intersecting with the sphere, and thereby can achieve higher rendering efficiency which is also suitable for graphics hardware acceleration. Then, a new method is designed for simulating interactions including water-rigid body interaction and rigid body-terrain interaction. Additionally, a general bubble and coast line rendering framework is provided. Experiments demonstrate that the proposed method can realize realistic rendering results with high rendering rates (FPS>60), and can be applied in real time scenarios such as computer games and virtual reality.
