		3×3 matrix datatype.
	</brief_description>
	<description>
		3×3 matrix used for 3D rotation and scale. Contains 3 vector fields X, Y and Z as its columns, which can be interpreted as the local basis vectors of a transformation. Can also be accessed as array of 3D vectors. These vectors are orthogonal to each other, but are not necessarily normalized (due to scaling). Almost always used as an orthogonal basis for a [Transform].
		For such use, it is composed of a scaling and a rotation matrix, in that order (M = R.S).

		<method name="get_euler">
			<return type="Vector3">
			</return>
			<description>
				Returns the basis's rotation in the form of Euler angles (in the YXZ convention: first Z, then X, and Y last). The returned vector contains the rotation angles in the format (X angle, Y angle, Z angle). See [method get_rotation_quat] if you need a quaternion instead.

		<method name="get_orthogonal_index">
			<return type="int">
			</return>
			<description>
				This function considers a discretization of rotations into 24 points on unit sphere, lying along the vectors (x,y,z) with each component being either -1, 0, or 1, and returns the index of the point best representing the orientation of the object. It is mainly used by the grid map editor. For further details, refer to the Godot source code.
			</description>
		</method>
		<method name="get_rotation_quat">
			<return type="Quat">
			</return>
			<description>
				Returns the basis's rotation in the form of a quaternion. See [method get_euler] if you need Euler angles, but keep in mind quaternions should generally be preferred to Euler angles.
