In this paper, real-time water rendering approaches using the graphics hardware is described. The key optical and motion characteristics of water are present. Although, the complex optical behavior and physical interactions can be calculated absolutely accurate, the computational capacity of today’s graphic cards is limited; the optimal compromise between realism and accuracy can be different depending on the target platform and required result. Perlin noise, which is one of the most commonly used approaches to simulate the wave animation, is introduced to avoid unnecessary computations. Rendering reflections and refractions is generally achieved by cube-maps simply. The demo applications demonstrate some discussed approaches and can be adjusted to various expectations.
