If you are interested in learning the basics of Computer Graphics, you will need to start learning the basics of Linear Algebra. Concepts such as vectors, matrices and transformations form the basics of computer graphics.
For example, when you press a button on your controller to rotate a game character on a screen, you are applying a rotational transformation to the...
