Transformation for 3-D Rotation
Rotation in 3-dimensions is considerably more complicated then rotation in 2-dimensions. In 2-Dimentional, a rotation is prescribed via an angle of rotation θ and a centre of rotation, as P.
Though, in 3-Dimentional rotations, we require to mention the angle of rotation and the axis of rotation. Because, we have now 3-axes, so the rotation can take place about any one of these axes. Hence, we have rotation about x-axis, y-axis, and z-axis correspondingly.
