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

<member name="rotation" type="Vector3" setter="set_rotation" getter="get_rotation">
Rotation part of the local transformation in radians, specified in terms of YXZ-Euler angles in the format (X-angle, Y-angle, Z-angle).
Note that in the mathematical sense, rotation is a matrix and not a vector. The three Euler angles, which are the three independent parameters of the Euler-angle parametrization of the rotation matrix, are stored in a [Vector3] data structure not because the rotation is a vector, but only because [Vector3] exists as a convenient data-structure to store 3 floating point numbers. Therefore, applying affine operations on the rotation "vector" is not meaningful.
