Accelerating and enhancing rendering of realistic ocean scenes
Résumé
Modeling and rendering realistic ocean scenes has been investigated by many researchers in the past few years, providing different models of ocean waves, fine scale details, and light water interactions.This paper describes a practical data structure for accelerating ray marching for a well known wave model defined as a sum of trochoids waves. This data structure exhibits nice properties that allow to take into account spatial and temporal coherence as well as reducing aliasing effects. In addition to this, it offers a unified frame workin which fine scale details,such as scattering phenomen a due to spray, foam or particles suspended in the water, can be added easily. Finally ,we present some benefit sof the model,which can handl e physically based light water interactions and glare effect
