conclude with the desired result of 3D rotation around a major axis. 2. 2D rotation of a point on the x-axis around the origin The goal is to rotate point P around the origin with angle α. Because we have the special case that P lies on the x-axis we see that x = r. Using basic school trigonometry, we conclude following formula from the diagram.A 3D rotation is defined by an angle and the rotation axis. Suppose we move a point Q given by the coordinates (x, y, z) about the x-axis to a new position given by (x', y,' z'). The x component of the point remains the same. Hence, this rotation is analogous to a 2D rotation in the y-z plane.
