Abstract
It is possible to generate synthetic images of the sea by creating a sea relief and by calculating its image using ray-tracing techniques. The sea surface is generated using sea wave statistics which are wind speed and direction dependent. A known power spectrum of the sea wave is used to filter white noise and the filtered noise is used as the sea relief. After that, the image of the sea is calculated using a ray-tracing technique which considers the emitted radiance of the sea, the specular reflection of the sky radiance and the reflection of the sun radiance (which is the sun irradiance scattered by the atmosphere). The resulting sun glint has been compared with the Cox and Munk model in order to make final adjustments to the simulation parameters. Thus, this model is able to produce images with well calibrated radiance and good sun glint distribution.
