Rotating with respect to a fixed axis.

[jeffreypaul15]

Is there a way to rotate an object only about one axis irrespective of the camera position?
For example :
I want to rotate this mesh only with respect to the z axis:

import pyvista
from pyvista import demos
pl = demos.orientation_plotter()
pl.camera.position = (0,3,0)
pl.camera.roll = 30
pl.show()

rotates the camera with respect to the x axis here

But

import pyvista
from pyvista import demos
pl = demos.orientation_plotter()
pl.camera.position = (3,0,0)
pl.camera.roll = 30
pl.show()

rotates the camera with respect to the z axis.

I wanted to know if there was a way to set roll to only rotate about one particular axis?
