Hydrax is a an add-on library for Ogre to render pretty water scenes.

With the Managed Hydrax -Wrapper (short form: MHydrax) Hydrax can be used by Mogre too.

I hope you enjoy MHydrax. Any feedback is welcome.

Things to do in Hydrax

Adjustments in *.cpp-files to work with Ogre 1.4x: (as told in this thread)

• Change these lines in MaterialManager::_createUnderwaterCompositor()

Ogre::PixelFormatList l;
    l.push_back(Ogre::PF_A8R8G8B8);
    TDef->formatList = l;

to:

TDef->format = Ogre::PF_A8R8G8B8; // New code line for Ogre 1.4.x

• Comment this line in Decal::setSize() if it's not already commented:

mProjector->setOrthoWindow(Size.x, Size.y);

• Optional: Change Hydrax to compile as static library (*.lib). (You may still choose to not do that...)

The result is that the managed MHydrax.dll doesn't need any native Hydrax.dll.

Things to do in MHydrax project properties

• In Framework and References: Adjust refence to Mogre.dll (the one corresponding to your current build mode)
• In C/C++: Adjust additional include directories to match yours
• In Linker: Adjust additional library directories to match yours

Things to do in Samples project properties

• In References: Adjust references to Mogre.dll and MOIS.dll (the ones corresponding to your current build mode)
• General things to do:
  • Copy folder "Media" from Hydrax to MHydrax solution directory or adjust the resources.cfg.
  • Make sure the dlls Ogre needs to run are in the debug/release folders. (OgreMain, OIS, OctreeSceneManager, CgProgramManager, cg, RenderSystems..)

Samples

An almost similar Samples project like in Hydrax is included. It's written in VB.NET code, but can be easily translated to C# or any other managed code language. For example by the VB.NET-to-C#-Converter: codeconverter.sharpdevelop.net.

Also you can look to the MHydrax code example.
