In three dimensions, we have a lot more freedom. We can obviously spin things around in the XY plane (around the z axis), XZ (around y), or in YZ (around x). It is also possible to dream up more complex rotations that touch all three coordinates at once, but they don’t add much value. They can be deconstructed into a sequence of planar rotations in XY, XZ, and YZ.
