In this chapter, we covered a lot of new material related to creating a 3D game. You learned how the game camera worked just like a video camera. Anything in the camera's frustum will be rendered to the screen. You also learned about the 3D coordinate system that is used to place objects in a 3D world. Finally, you learned about matrices and vectors, which form the underpinning of how 3D objects are manipulated.

Finally, we started with a blank project and walked through all of the code required to set up a 3D game that will use OpenGL to render. Remember, you will never have to memorize this code! But, it is important that you have a basic understanding of what purpose each line of code serves.

In the next chapter, you will learn to create and load 3D models from modeling program.
