- 11. Pop quiz — Answers
This chapter will introduce us to the concept of a scene graph and how we can use its functions to create complex scenes.
In this chapter, we will:
- Learn the three basic operations in 3D space
- How a scene graph is organized
- The different 3D spaces we can operate in
So let's get on with it.
In the last chapter, Chapter 1, Installing Ogre 3D, we loaded a 3D model and attached it to our scene. Now we will learn how to create a new scene node and attach our 3D model to it.
