WebRotation matrices have explicit formulas, e.g.: a 2D rotation matrix for angle a is of form: cos (a) -sin (a) sin (a) cos (a) There are analogous formulas for 3D, but note that 3D rotations take 3 parameters instead of just 1. Translations are less trivial and will be discussed later. They are the reason we need 4D matrices.
