<member name="basis" type="Basis" setter="set_basis" getter="get_basis">
Direct access to the 3x3 basis of the [Transform3D] property.
</member>
<member name="global_position" type="Vector3" setter="set_global_position" getter="get_global_position">
Global position of this node. This is equivalent to [code]global_transform.origin[/code].
</member>
<member name="global_rotation" type="Vector3" setter="set_global_rotation" getter="get_global_rotation">
Rotation part of the global transformation in radians, specified in terms of YXZ-Euler angles in the format (X angle, Y angle, Z angle).
[b]Note:[/b] 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.
