- 11. Pop quiz — Answers
Ogre 3D offers a lot of functionalities. In this chapter, we are going to touch on some techniques we haven't used before, but ones that are extremely useful for creating complex 3D scenes such as
SceneManagers, creating our own models, speeding up our application, and efficiently rendering large chunks of 3D data.
In this chapter, we will:
- Learn how to change the current scene manager
- Learn what an Octree is
- Learn how to create our own entities in code
- Learn how to speed up our application using static geometry
So let's get on with it...
