The Lightfeather 3D Engine was created as the successor to IrrlichtNX++.
This step was taken after the differences between IrrlichtNX++ and Irrlicht grew
bigger and bigger. So to not misrepresent the engine as being somewhat close to
Irrlicht, the name was changed.
There are still some things in Lightfeather that were taken from Irrlicht but
the main parts are completely written from scratch.
The Irrlicht engine is (c) 2002-2005 by Nikolaus Gebhart and the website for
it is irrlicht.sourceforge.net.
