lerp()

function lerp	(	local	other,
		local	t
	)

Interpolates between two quaternions using linear interpolation.

The interpolation curve for linear interpolation between

quaternions gives a straight line in quaternion space.

(

local

other

)

function normalize

(

)

set()

function set

(

local ...

)

setIdentity()

function setIdentity

(

)

slerp()

function slerp	(	local	other,
		local	t
	)

Interpolates between two quaternions using spherical linear interpolation.

Spherical linear interpolation provides smooth transitions between different

orientations and is often useful for animating models or cameras in 3D.

Note: For accurate interpolation, the input quaternions must be at (or close to) unit length.

This method does not automatically normalize the input quaternions, so it is up to the

caller to ensure they call normalize beforehand, if necessary.

squad()

static function squad	(	local	q1,
		local	q2,
		local	s1,
		local	s2,
		local	t
	)

Interpolates over a series of quaternions using spherical spline interpolation.

Spherical spline interpolation provides smooth transitions between different

orientations and is often useful for animating models or cameras in 3D.

Note: For accurate interpolation, the input quaternions must be unit.

This method does not automatically normalize the input quaternions,

so it is up to the caller to ensure they call normalize beforehand, if necessary.

toAxisAngle()

function toAxisAngle

(

)

Converts this Quaternion4f to axis-angle notation. The axis is normalized.

Returns

math.vec3, number

zero()

static function zero
