Methods

---

<static> fromAxisAngle()

Creates a new Quaternion from an axis/angle rotation.

---

<static> fromEuler()

Creates a new Quaternion from Euler angles.

---

<static> fromMatrix()

Creates a new Quaternion from a rotation matrix.

---

<static> fromPitchYawRoll()

Creates a new Quaternion from pitch/yaw/roll Tait Bryan angles.

---

<static> fromVectors()

Creates a new Quaternion that rotates v1 to v2

---

append()

Post-multiplies another quaternion to this one.

---

conjugate()

Converts to the conjugate.

---

copyFrom()

Copies all components from another quaternion

---

fromAxisAngle()

Initializes as an axis/angle rotation

---

fromEuler()

Initializes from Euler angles

---

fromMatrix()

Initializes from a rotation matrix

---

fromPitchYawRoll()

Initializes from Tait-Bryan angles

---

inverseOf()

Stores the inverse of a given quaternion.

---

invert()

Inverts the quaternion.

---

lerp(a, b, t)

Linearly interpolates two quaternions.

Parameters:

Name	Type	Description
a	Quaternion	The first vector to interpolate from.
b	Quaternion	The second vector to interpolate to.
t	Number	The interpolation factor.

---

multiply()

Multiplies two quaternions and stores it in the current.

---

negate()

Negates all the components. This results in the same net rotation, but with different orientation

---

normalize()

Normalizes the quaternion.

---

prepend()

Pre-multiplies another quaternion to this one.

---

rotate( [target])

Rotates a Float4 point.

Parameters:

Name	Type	Argument	Description
target	Float4	<optional>	An optional target object. If not provided, a new object will be created and returned.

---

set()

Sets all components explicitly

---

slerp(a, b, t)

Spherical-linearly interpolates two quaternions.

Parameters:

Name	Type	Description
a	Quaternion	The first vector to interpolate from.
b	Quaternion	The second vector to interpolate to.
t	Number	The interpolation factor.

---

toEuler()

Stores the rotation as Euler angles in a Float4 object
