/** Example 002 Quake3Map

This Tutorial shows how to load a Quake 3 map into the engine, create a
SceneNode for optimizing the speed of rendering, and how to create a user
controlled camera.

Please note that you should know the basics of the engine before starting this
tutorial. Just take a short look at the first tutorial, if you haven't done
this yet: http://irrlicht.sourceforge.net/tut001.html  

Lets start like the HelloWorld example: We include the irrlicht header files
and an additional file to be able to ask the user for a driver type using the
console.

As already written in the HelloWorld example, in the Irrlicht Engine everything
can be found in the namespace 'irr'. To get rid of the irr:: in front of the
name of every class, we tell the compiler that we use that namespace from now
on, and we will not have to write that 'irr::'. There are 5 other sub
namespaces 'core', 'scene', 'video', 'io' and 'gui'. Unlike in the HelloWorld
example, we do not call 'using namespace' for these 5 other namespaces, because
in this way you will see what can be found in which namespace. But if you like,
you can also include the namespaces like in the previous example.

  Now we can load the mesh by calling

  some materials attached. Hence the IAnimatedMesh consists of only one
  frame, so we get the "first frame" of the "animation", which is our
  quake level and create an OctTree scene node with it, using
  irr::scene::ISceneManager::addOctTreeSceneNode().
  The OctTree optimizes the scene a little bit, trying to draw only geometry
  which is currently visible. An alternative to the OctTree would be a
  irr::scene::IMeshSceneNode, which would always draw the complete
  geometry of the mesh, without optimization. Try it: Use
  irr::scene::ISceneManager::addMeshSceneNode() instead of
  addOctTreeSceneNode() and compare the primitives drawn by the video
  driver. (There is a irr::video::IVideoDriver::getPrimitiveCountDrawn()
  method in the irr::video::IVideoDriver class). Note that this
  optimization with the OctTree is only useful when drawing huge meshes
  consisting of lots of geometry.
