Struct Quaternion 

pub struct Quaternion {
    pub x: f32,
    pub y: f32,
    pub z: f32,
    pub w: f32,
}

A rotation as a unit quaternion.

Flutter counterpart: Quaternion (package:vector_math), narrowed to the f32 the host’s Matrix4 stores.

Fields

x: f32

The first imaginary component.

y: f32

The second imaginary component.

z: f32

The third imaginary component.

w: f32

The real component.

Implementations

impl Quaternion

pub const IDENTITY: Quaternion

The rotation that changes nothing.

pub const fn new(x: f32, y: f32, z: f32, w: f32) -> Quaternion

Constructs a quaternion from its four components.

pub fn length(&self) -> f32

The norm of the quaternion.

pub fn length2(&self) -> f32

The squared norm of the quaternion.

pub fn scaled(&self, scale: f32) -> Quaternion

A copy of this scaled by scale.

pub fn normalized(&self) -> Quaternion

A copy of this with unit length.

A zero-length quaternion is returned unchanged, as Quaternion.normalize leaves it.

Trait Implementations

impl Add for Quaternion

type Output = Quaternion

The resulting type after applying the + operator.

fn add(self, other: Quaternion) -> Quaternion

Performs the + operation.

impl Clone for Quaternion

fn clone(&self) -> Quaternion

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Quaternion

impl Debug for Quaternion

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Default for Quaternion

fn default() -> Quaternion

Returns the “default value” for a type.

impl PartialEq for Quaternion

fn eq(&self, other: &Quaternion) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool
