osgOcean v1.0
-------------

DEPENDANCIES
------------

Resources
---------

Both the library and the example require a set of resource
files (models/textures) which can be downloaded from here:
http://osgocean.googlecode.com/files/osgOcean-Resources-1.0.rar

Once you downloaded them, extract the 'Island' and 'Textures' 
folders into the resources directory found in the root of the
source code tree. The install project will copy the relevant
data files to the bin path like so:

*install_path*/bin/resources/

osgOcean uses the osgDB registry to find the resource files.
By default it adds the following paths to the registry:

Shader path:
resources/shaders/

Texture path:
resources/textures/

If you wish to move these resources you must update the data file path 
list within the registry yourself. This can be down from outside the 
library with the following code:

osgDB::FilePathList& pathList = osgDB::Registry::instance()->getDataFilePathList();
pathList.push_back( new_path );
