Hydrax is an add-on for Ogre which aim is to provide an easy-use library in order to render pretty water scenes.
It's fully configurable, all effect, such as water depth effects, smooth transitions, foam effects, caustics, underwater god rays, ... can be modified in real-time as well as all options that do not depend of shaders such as Rtt's texture quality, hydrax geometry and noise modules options, you can change between different modules(geometry and noise) on-fly, etc... Hydrax has a modulable interface wich allows any kind of water geometry, actually there're three modules availables: The infinite ocean module, based on the projected grid concept, the simple grid module and the radial grid module; of course, hydrax geometry modules and noise modules can be coded by users.
Underwater rendering: (With underwater reflections and sun god rays!)

Main features
- Realistic fresnel refraction and reflection effects
- Intelligent depth effects based on depth maps
- Smooth transitions effects: Smooth transitions with all objects in the scene using the depth map
- Caustics effects
- Sunlight effects (Colour, Position, Sun strength, area, etc...)
- Full underwater effects like underwater reflections, god rays...
- Foam effects
- Water editor
- Vertex and GPU Normals generation
- Decals support (to place any kind of texture on the water, like ship trails, water vegetables, etc)
- Modulable interface (Geometry and noise modules)
- HLSL and CG support (and GLSL in future versions)
Geometry modules:
- Projected grid
- Simple grid
- Radial grid
Noise modules:
- Perlin
- FFT

A Managed Hydrax Wrapper for use with MOGRE is also available.

Roadmap
Version 0.6:
Library:
- Improve underwater rendering. Update underwater depth calculations based on the distance, like the Crysis(Crytek) approach.
- Improve Perlin and FFT normal map generator shaders
Editor:
Demo:
Examples:
- Advanced example: using custom textures for depth calculations(0.5 version feature)
- Advanced example: creating ship trails(decals).
Tutorials:
- Creating custom geometry and noise modules
