      3D Rotation – –exam, idea of three matrices for the three rotations. In 3D, rotation matrices describing rotations about the Z, X, and Y axes look like this, as given in the course notes for CS 405. To understand why these matrices are 4-dimensional instead of 3, read about homogeneous coordinates in the course notes for CS 405.
