Struct pathfinder_geometry::vector::Vector4F

pub struct Vector4F(pub F32x4);

3D homogeneous points.

Methods

impl Vector4F

pub fn new(x: f32, y: f32, z: f32, w: f32) -> Vector4F

pub fn splat(value: f32) -> Vector4F

pub fn to_2d(self) -> Vector2F

pub fn to_3d(self) -> Vector3F

Performs perspective division to convert this vector to 3D.

pub fn x(self) -> f32

pub fn y(self) -> f32

pub fn z(self) -> f32

pub fn w(self) -> f32

pub fn scale(self, x: f32) -> Vector4F

pub fn set_x(&mut self, x: f32)

pub fn set_y(&mut self, y: f32)

pub fn set_z(&mut self, z: f32)

pub fn set_w(&mut self, w: f32)

pub fn approx_eq(self, other: Vector4F, epsilon: f32) -> bool

pub fn is_zero(self) -> bool

Checks to see whether this homogeneous coordinate equals zero.

Note that since this treats the coordinate as a homogeneous coordinate, the w is ignored.

pub fn lerp(self, other: Vector4F, t: f32) -> Vector4F

Trait Implementations

impl Add<Vector4F> for Vector4F

type Output = Vector4F

The resulting type after applying the + operator.

fn add(self, other: Vector4F) -> Vector4F

Performs the + operation.

impl AddAssign<Vector4F> for Vector4F

fn add_assign(&mut self, other: Vector4F)

Performs the += operation.

impl Clone for Vector4F

fn clone(&self) -> Vector4F

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Copy for Vector4F

impl Debug for Vector4F

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

Formats the value using the given formatter.

impl Default for Vector4F

fn default() -> Vector4F

Returns the "default value" for a type.

impl Mul<Vector4F> for Transform4F

type Output = Vector4F

The resulting type after applying the * operator.

fn mul(self, vector: Vector4F) -> Vector4F

Performs the * operation.

impl Mul<Vector4F> for Vector4F

type Output = Vector4F

The resulting type after applying the * operator.

fn mul(self, other: Vector4F) -> Vector4F

Performs the * operation.

impl Neg for Vector4F

type Output = Vector4F

The resulting type after applying the - operator.
