Realistic Real-time Underwater Caustics and

Realistic rendering of underwater scenes has been a subject of increasing importance in modern real-time 3D applications, s uch as open-world 3D games, which constantly present the user with opportunities to submerge oneself in an underwater environme nt. Crucial to the accurate recreation of these environments are th e ffects of caustics and godrays. In this paper, we shall present a nov el algorithm, for physically inspired real-time simulation of t hese phenomena, on commodity 3D graphics hardware, which can easily be integrated in a modern 3D engine.
