The behaviour of fluids in the physical world is governed by the laws of fluid dynamics. The proposed shader is evaluated using a range of test scenarios and compared against existing solutions to demonstrate its effectiveness and efficiency. Through a detailed analysis of existing techniques, I propose a novel approach that combines physically-based modelling with procedural generation to achieve a realistic and visually stunning water surface. The focus is on creating a visually compelling and interactive water surface that responds to user interaction and environmental factors, while balancing performance requirements. This article explores the development of dynamic fluid-based shaders that can visually simulate realistic water behaviour, such as waves, refraction, reflection, depth, fog, caustics and more. Dynamic fluid-based shaders offer a flexible and efficient solution for rendering water in real-time applications. Fluid is a ubiquitous element in many virtual environments, and achieving realistic rendering is a key challenge for game and film developers.
