+ The [Quaternion] built-in [Variant] type is a 4D data structure that represents rotation in the form of a [url=https://en.wikipedia.org/wiki/Quaternions_and_spatial_rotation]Hamilton convention quaternion[/url]. Compared to the [Basis] type which can store both rotation and scale, quaternions can [i]only[/i] store rotation.

+ A [Quaternion] is composed by 4 floating-point components: [member w], [member x], [member y], and [member z]. These components are very compact in memory, and because of this some operations are more efficient and less likely to cause floating-point errors. Methods such as [method get_angle], [method get_axis], and [method slerp] are faster than their [Basis] counterparts.

+ For a great introduction to quaternions, see [url=https://www.youtube.com/watch?v=d4EgbgTm0Bg]this video by 3Blue1Brown[/url]. You do not need to know the math behind quaternions, as Godot provides several helper methods that handle it for you. These include [method slerp] and [method spherical_cubic_interpolate], as well as the [code]*[/code] operator.

+ [b]Note:[/b] Quaternions must be normalized before being used for rotation (see [method normalized]).

+ [b]Note:[/b] Similarly to [Vector2] and [Vector3], the components of a quaternion use 32-bit precision by default, unlike [float] which is always 64-bit. If double precision is needed, compile the engine with the option [code]precision=double[/code].

+ Constructs a [Quaternion] identical to the [constant IDENTITY].

+ Constructs a [Quaternion] representing the shortest arc between [param arc_from] and [param arc_to]. These can be imagined as two points intersecting a sphere's surface, with a radius of [code]1.0[/code].

+ Constructs a [Quaternion] representing rotation around the [param axis] by the given [param angle], in radians. The axis must be a normalized vector.

+ Constructs a [Quaternion] from the given rotation [Basis].

+ This constructor is faster than [method Basis.get_rotation_quaternion], but the given basis must be [i]orthonormalized[/i] (see [method Basis.orthonormalized]). Otherwise, the constructor fails and returns [constant IDENTITY].

+ Constructs a [Quaternion] defined by the given values.

+ [b]Note:[/b] Only normalized quaternions represent rotation; if these values are not normalized, the new [Quaternion] will not be a valid rotation.

+ Returns the dot product between this quaternion and [param with].

+ This is equivalent to [code](quat.x * with.x) + (quat.y * with.y) + (quat.z * with.z) + (quat.w * with.w)[/code].

+ Constructs a new [Quaternion] from the given [Vector3] of [url=https://en.wikipedia.org/wiki/Euler_angles]Euler angles[/url], in radians. This method always uses the YXZ convention ([constant EULER_ORDER_YXZ]).

+ Returns this quaternion's rotation as a [Vector3] of [url=https://en.wikipedia.org/wiki/Euler_angles]Euler angles[/url], in radians.

+ The order of each consecutive rotation can be changed with [param order] (see [enum EulerOrder] constants). By default, the YXZ convention is used ([constant EULER_ORDER_YXZ]): Z (roll) is calculated first, then X (pitch), and lastly Y (yaw). When using the opposite method [method from_euler], this order is reversed.

+ Returns the inverse version of this quaternion, inverting the sign of every component except [member w].

+ Returns [code]true[/code] if this quaternion is normalized. See also [method normalized].

+ Returns this quaternion's length, also called magnitude.

+ Returns this quaternion's length, squared.

+ [b]Note:[/b] This method is faster than [method length], so prefer it if you only need to compare quaternion lengths.

+ Returns the logarithm of this quaternion. Multiplies this quaternion's rotation axis by its rotation angle, and stores the result in the returned quaternion's vector part ([member x], [member y], and [member z]). The returned quaternion's real part ([member w]) is always [code]0.0[/code].

+ Returns a copy of this quaternion, normalized so that its length is [code]1.0[/code]. See also [method is_normalized].

+ Performs a spherical-linear interpolation with the [param to] quaternion, given a [param weight] and returns the result. Both this quaternion and [param to] must be normalized.

+ Performs a spherical-linear interpolation with the [param to] quaternion, given a [param weight] and returns the result. Unlike [method slerp], this method does not check if the rotation path is smaller than 90 degrees. Both this quaternion and [param to] must be normalized.

+ W component of the quaternion. This is the "real" part.

+ [b]Note:[/b] Quaternion components should usually not be manipulated directly.

+ X component of the quaternion. This is the value along the "imaginary" [code]i[/code] axis.

+ [b]Note:[/b] Quaternion components should usually not be manipulated directly.

+ Y component of the quaternion. This is the value along the "imaginary" [code]j[/code] axis.

+ [b]Note:[/b] Quaternion components should usually not be manipulated directly.

+ Z component of the quaternion. This is the value along the "imaginary" [code]k[/code] axis.

+ [b]Note:[/b] Quaternion components should usually not be manipulated directly.

+ The identity quaternion, representing no rotation. This has the same rotation as [constant Basis.IDENTITY].

+ If a [Vector3] is rotated (multiplied) by this quaternion, it does not change.

+ Returns [code]true[/code] if the components of both quaternions are not exactly equal.

+ Composes (multiplies) two quaternions. This rotates the [param right] quaternion (the child) by this quaternion (the parent).

+ Rotates (multiplies) the [param right] vector by this quaternion, returning a [Vector3].

+ Multiplies each component of the [Quaternion] by the right [float] value.

+ This operation is not meaningful on its own, but it can be used as a part of a larger expression.

+ Multiplies each component of the [Quaternion] by the right [int] value.

+ This operation is not meaningful on its own, but it can be used as a part of a larger expression.

+ Adds each component of the left [Quaternion] to the right [Quaternion].

+ This operation is not meaningful on its own, but it can be used as a part of a larger expression, such as approximating an intermediate rotation between two nearby rotations.

+ Subtracts each component of the left [Quaternion] by the right [Quaternion].

+ This operation is not meaningful on its own, but it can be used as a part of a larger expression.

+ Divides each component of the [Quaternion] by the right [float] value.

+ This operation is not meaningful on its own, but it can be used as a part of a larger expression.

+ Divides each component of the [Quaternion] by the right [int] value.

+ This operation is not meaningful on its own, but it can be used as a part of a larger expression.

+ Returns [code]true[/code] if the components of both quaternions are exactly equal.

+ Accesses each component of this quaternion by their index.

+ Index [code]0[/code] is the same as [member x], index [code]1[/code] is the same as [member y], index [code]2[/code] is the same as [member z], and index [code]3[/code] is the same as [member w].

+ Returns the negative value of the [Quaternion]. This is the same as multiplying all components by [code]-1[/code]. This operation results in a quaternion that represents the same rotation.
