<p>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 also an editor
|
||
|
|
available to edit those files, named irrEdit on <a href="http://www.ambiera.com/irredit" target="_blank">http://www.ambiera.com/irredit</a>,
|
||
|
|
which can also be used as world and particle editor. This tutorial shows
|
||
|
|
how to use .irr files.</p>

<p>Now load our .irr file. .irr files can store the whole scene graph
|
||
|
|
including animators, materials and particle systems. And there is also
|
||
|
|
the possibility to store arbitrary user data for every scene node in
|
||
|
|
that file. To keep this example simple, we are simply loading the scene
|
||
|
|
here. See the documentation at ISceneManager::loadScene and ISceneManager::saveScene
|
||
|
|
for more information. So to load and display a complicated huge scene,
|
||
|
|
we only need a single call to loadScene().</p>
