FQuaternion

Description

Quaternions are used to represent rotations.

Static Properties	Description	Quaternion	FQuaternion
identity	The identity rotation (Read Only).

Properties	Description	Quaternion	FQuaternion
eulerAngles	Returns or sets the euler angle representation of the rotation.
normalized	Returns this quaternion with a magnitude of 1 (Read Only).
this[int]	Access the x, y, z, w components using [0], [1], [2], [3] respectively.
w	W component of the Quaternion. Do not directly modify quaternions.
x	X component of the Quaternion. Don't modify this directly unless you know quaternions inside out.
y	Y component of the Quaternion. Don't modify this directly unless you know quaternions inside out.
z	Z component of the Quaternion. Don't modify this directly unless you know quaternions inside out.

Constructors	Description	Quaternion	FQuaternion
Quaternion	Constructs new Quaternion with given x,y,z,w components.
FQuaternion	Constructs new Quaternion with given x,y,z,w components.

Public Methods	Description	Quaternion	FMaFQuaternionth
Set	Set x, y, z and w components of an existing Quaternion.
SetFromToRotation	Creates a rotation which rotates from fromDirection to toDirection.
SetLookRotation	Creates a rotation with the specified forward and upwards directions.
ToAngleAxis	Converts a rotation to angle-axis representation (angles in degrees).
ToString	Returns a formatted string of the Quaternion.

Static Methods	Description	Quaternion	FQuaternion
Angle	Returns the angle in degrees between two rotations a and b.
AngleAxis	Creates a rotation which rotates angle degrees around axis.
Dot	The dot product between two rotations.
Euler	Returns a rotation that rotates z degrees around the z axis, x degrees around the x axis, and y degrees around the y axis; applied in that order.
FromToRotation	Creates a rotation which rotates from fromDirection to toDirection.
Inverse	Returns the Inverse of rotation.
Lerp	Interpolates between a and b by t and normalizes the result afterwards. The parameter t is clamped to the range [0, 1].
LerpUnclamped	Interpolates between a and b by t and normalizes the result afterwards. The parameter t is not clamped.
LookRotation	Creates a rotation with the specified forward and upwards directions.
Normalize	Converts this quaternion to one with the same orientation but with a magnitude of 1.
RotateTowards	Rotates a rotation from towards to.
Slerp	Spherically interpolates between quaternions a and b by ratio t. The parameter t is clamped to the range [0, 1].
SlerpUnclamped	Spherically interpolates between a and b by t. The parameter t is not clamped.

Operators	Description	Quaternion	FQuaternion
operator *	Combines rotations lhs and rhs.
operator ==	Are two quaternions equal to each other?
