Struct Vec3 

pub struct Vec3 {
    pub x: f32,
    pub y: f32,
    pub z: f32,
}

A 3D vector for positions and directions.

Fields

x: f32

X component.

y: f32

Y component.

z: f32

Z component.

Implementations

impl Vec3

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

Create a new vector.

pub const fn zero() -> Self

Zero vector.

pub const fn up() -> Self

Unit vector pointing up (Y+).

pub const fn forward() -> Self

Unit vector pointing forward (Z-).

pub fn length(&self) -> f32

Calculate the length (magnitude) of the vector.

pub fn normalize(&self) -> Self

Normalize the vector to unit length.

pub fn cross(&self, other: &Self) -> Self

Cross product of two vectors.

pub fn dot(&self, other: &Self) -> f32

Dot product of two vectors.

pub fn sub(&self, other: &Self) -> Self

Subtract two vectors.

pub fn add(&self, other: &Self) -> Self

Add two vectors.

pub fn scale(&self, s: f32) -> Self

Scale vector by a scalar.

Trait Implementations

impl Clone for Vec3

fn clone(&self) -> Vec3

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Vec3

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

Formats the value using the given formatter.

impl Default for Vec3

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Vec3

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Vec3

fn eq(&self, other: &Vec3) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Vec3

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Vec3
