	</brief_description>
	<description>
		Most basic 3D game object, with a 3D [Transform] and visibility settings. All other 3D game objects inherit from Spatial. Use [Spatial] 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 [Spatial] object is set as top-level. Affine operations in this coordinate system correspond to direct affine operations on the [Spatial]'s transform. The word local below refers to this coordinate system. The coordinate system that is attached to the [Spatial] 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 @GDScript.deg2rad].

	<methods>
		<method name="force_update_transform">
			<return type="void" />
			<description>
				Forces the transform to update. Transform changes in physics are not instant for performance reasons. Transforms are accumulated and then set. Use this if you need an up-to-date transform when doing physics operations.
			</description>
		</method>
		<method name="get_global_transform_interpolated">
			<return type="Transform" />
			<description>
				When using physics interpolation, there will be circumstances in which you want to know the interpolated (displayed) transform of a node rather than the standard transform (which may only be accurate to the most recent physics tick).
				This is particularly important for frame-based operations that take place in [method Node._process], rather than [method Node._physics_process]. Examples include [Camera]s focusing on a node, or finding where to fire lasers from on a frame rather than physics tick.
				[b]Note:[/b] This function creates an interpolation pump on the [Spatial] the first time it is called, which can respond to physics interpolation resets. If you get problems with "streaking" when initially following a [Spatial], be sure to call [method get_global_transform_interpolated] at least once [i]before[/i] resetting the [Spatial] physics interpolation.
