| | ''rot'' | 1x4 vector | Prescribed rotation. Values represent the target orientation of the node in 3-D space, according to the [[https://en.wikipedia.org/wiki/Rotation_formalisms_in_three_dimensions#Euler_axis_and_angle_.28rotation_vector.29|axis-angle notation]]. The first value represents the rotation angle (in radians) and the second to fourth values the normalized axis of rotation. Note that this input complete defines and constrains the orientation of the node, i.e. no other simultaneous rotations of the node are possible. | | | ''rot'' | 1x4 vector | Prescribed rotation.
