Reections are produced by ipping the original camera vertically and rendering the
needed objects to a new framebuer, which has a lower resolution for greater performance.
SSS simulation is based on light and camera directions and surface normals [Seymour 12].
ese simple calculations give us surprisingly realistic results.
Foam is inuenced by three major factors used for mixing with the original color:
1. High waves
2. Rolling waves with a normal close to the direction toward the shore
3. Depth-based foam on objects close to the surface of the water

When water mesh vertices reach a specic height, ...
