   Before you start creating your game, you should plan your scene graph: Which Nodes and Geometries will you need? Complete the xref:tutorials:beginner.adoc[Beginner tutorials] to learn how to load and create Spatials, how to lay out a scene by attaching, detaching, and transforming Spatials, and how to add interaction and effects to a game.

  These default settings are called "`WASD`" keys and "`Mouse`" Look. You can customize <<jme3/advanced/input_handling#,input handling>> for your game. Sorry, but these settings work best on a QWERTY/QWERTZ keyboard.
  
  
  == Scene Graph and RootNode
  
  The _scene graph_ represents your 3D world. Objects in the jME3 scene graph are called <<jme3/advanced/spatial#,Spatial>>s. Everything attached to the parent _rootNode_ is part of your scene. Your game inherits the `rootNode` object from the `SimpleApplication` class.

  Before you start making games, make sure you understand general xref:tutorials:terminology.adoc[3D Graphics terminology].
  
  Second, if you are a beginner, we recommend our xref:tutorials:scenegraph_for_dummies.adoc[Scene Graph for Dummies] presentation for a visual introduction to the concept of a scene graph.
