Simulating water in 3D rendering is complex due to its dynamic and transparent nature, which interacts with light intricately. Creating realistic water requires consideration of several properties, including transparency, reflections, refractions, surface ripples, and caustics.
The implementation of realistic water in 3D rendering typically requires a blend of shader programming, texture mapping, environmental mapping, and sophisticated rendering algorithms. As modern rendering engines progress, they provide enhanced water simulations for a more immersive visual experience.
