This thesis presents a system for procedural terrain and coral generation, simulation of waves, rendering of liquid environments, and introduces a new approach to generating water organisms like corals based on reaction-diffusion systems. In liquid environments, different optical and physical effects are visible, such as light scattering, absorption, turbulence, and the existence of other particles in the media. To render these visual effects we use different techniques, which are then combined into a single model for simulating liquid environments. Special attention was given to the transition between air and water. The application was implemented in the Unity game engine with the goal of real-time execution for use in interactive applications.
