Irrlicht Engine

Code: Select all

/*
Since version 1.1, Irrlicht is able to save and load
the full scene graph into an .irr file, an xml based
format. There is an editor available to edit
those files, named irrEdit on http://www.ambiera.com/irredit,
which can also be used as world and particle editor.
This tutorial shows how to use .irr files.

Lets start: Create an Irrlicht device and setup the window.
