	</brief_description>
	<description>
		Most basic 3D game object, with a 3D [Transform] and visibility settings. All other 3D game objects inherit from Node3D. Use [Node3D] as a parent node to move, scale, rotate and show/hide children in a 3D project.
		Affine operations (rotate, scale, translate) happen in parent's local coordinate system, unless the [Node3D] object is set as top-level. Affine operations in this coordinate system correspond to direct affine operations on the [Node3D]'s transform. The word local below refers to this coordinate system. The coordinate system that is attached to the [Node3D] object itself is referred to as object-local coordinate system.
		[b]Note:[/b] Unless otherwise specified, all methods that have angle parameters must have angles specified as [i]radians[/i]. To convert degrees to radians, use [method @GlobalScope.deg2rad].

Therefore, applying affine operations on the rotation "vector" is not meaningful.
