3D Math Review
Robert Chin · Apress eBooks · 2014
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. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
