Struct Vec3

pub struct Vec3 {
    pub e: [f64; 3],
}

A 3D vector with f64 components.

Fields

e: [f64; 3]

Components stored as [x, y, z].

Implementations

impl Vec3

pub fn new(e0: f64, e1: f64, e2: f64) -> Self

Creates a new Vec3 from three f64 components.

pub fn x(self) -> f64

Returns the x component.

pub fn y(self) -> f64

Returns the y component.

pub fn z(self) -> f64

Returns the z component.

pub fn length_squared(self) -> f64

Returns the squared length (dot product with itself).

pub fn length(self) -> f64

Returns the Euclidean length.

pub fn near_zero(self) -> bool

Returns true if all components are very close to zero (zero-vector check).

Trait Implementations

impl Add for Vec3

type Output = Vec3

The resulting type after applying the + operator.

fn add(self, v: Vec3) -> Vec3

Performs the + operation.

impl AddAssign for Vec3

Formats the value using the given formatter.

impl Div<f64> for Vec3

type Output = Vec3

The resulting type after applying the / operator.

fn div(self, t: f64) -> Vec3

Performs the / operation.

impl DivAssign<f64> for Vec3

fn div_assign(&mut self, t: f64)

Performs the /= operation.

type Output = f64

The returned type after indexing.

fn index(&self, i: usize) -> &f64

Performs the indexing (container[index]) operation.

impl IndexMut<usize> for Vec3

fn index_mut(&mut self, i: usize) -> &mut f64

Performs the mutable indexing (container[index]) operation.

impl Mul<Vec3> for f64

type Output = Vec3

The resulting type after applying the * operator.

fn mul(self, v: Vec3) -> Vec3

Performs the * operation.

impl Mul<f64> for Vec3

type Output = Vec3

The resulting type after applying the * operator.

fn mul(self, t: f64) -> Vec3
