/*
This tutorial will show how to implement a camera and character display which is a copy of the
one used in World of Warcraft.
Its purpose is to offer the Community an example for a camera and movement system for rpg or 
as a base to develop theyr own movement/camera system.

It is based on the irrlicht Tutorial 12 and 
NightBirds NWN Camera example http://irrlicht.sourceforge.net/phpBB2/viewtopic.php?t=3245

Atm its all a bitt messy and very unclean but its still work in progress , althought comments 
or suggestions are always welcome.
You can contact me in the Irrlicht Forums
