Sets the axis-angle rotation effect of the operator.
If this is a rotation operator, the command will set the axis-angle rotation.
male = viz.addAvatar( 'vcc_male.cfg' )
viewLink = viz.link( male, viz.MainView )
rotateOperator = viewLink.preEuler([0, 40, 0])
rotateOperator.setAxisAngle([0, 0, 1, 20]) #Change rotation amount
