  When creating a 3D game
  
  .  You create some scene objects like players, buildings, etc.
  .  You add the objects to the scene.
  .  You move, resize, rotate, color, and animate them.
  
  You will learn that the scene graph represents the 3D world, and why the rootNode is important. You will learn how to create simple objects, how to let them carry custom data (such as health points), and how to "`transform`" them by moving, scaling, and rotating. You will understand the difference between the two types of "`Spatials`" in the scene graph: Nodes and Geometries.
