Besides the Vector Mapping node, if we want to rotate vectors,

we can also use the Vector Rotate node. Most often we would use this to rotate texture coordinates.

By default, it's set to the Axis Angle mode, which allows us to define an axis around which

to rotate our vectors. The default axis has a value of one for Z, and zero for X and Y.

This makes it an axis pointing straight up in the Z direction,

so by changing the angle, we're rotating around the Z axis. But importantly, we can

change this axis to point in any direction, not just one of the three primary axes.

In fact, if we want to rotate around one of the primary axes,

it's more convenient to switch the rotation mode from Axis Angle to one of the fixed axis modes.

These allow us to rotate directly around X, Y or Z, without having to specify an axis vector.

And finally, the Euler mode allows us to specify an angle for each axis,

just like the rotation property of an object does by default.

Also note that in any of the rotation modes,

we can specify the rotation pivot to be anywhere, by changing the Center parameter.
