Chapter 3
3D Math Review
In this chapter, I cover vectors and matrices. Vectors and matrices are key to 3D game programming in terms of such things as determining the placement of 3D objects in the scene and how a 3D object is projected onto a 2D screen. Vectors can also be used for defining properties such as velocity and force. I start by discussing vectors and operations that can be performed with vectors. I then cover matrices and the essential operations related to 3D graphics that can be performed with matrices. Finally, I present a hands-on example that will demonstrate how vectors and matrices are actually used in a real 3D graphics program on an Android device.
