Type Alias Vec3 

pub type Vec3<T = f32> = Vector<T, 3>;

A 3D vector

Aliased Type

pub struct Vec3<T = f32>(/* private fields */);

Implementations

impl<T: Copy + NumAssign> Vec3<T>

pub fn from_vec2(v: Vec2<T>, z: T) -> Self

Creates a new Vec3 from a Vec2 and z component.

Examples

let v = Vec2::<i32>::from_slice(&[2, 3]);
assert_eq!(*Vec3::<i32>::from_vec2(v, 4).as_ref(), [2, 3, 4]);

pub fn xy(&self) -> Vec2<T>

Returns a copy of the xy components as a Vec2.

Examples

let v = Vec3::<i32>::from_slice(&[2, 3, 4]);
assert_eq!(*v.xy().as_ref(), [2, 3]);

impl<T: Copy + NumAssign> Vec3<T>

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

Calculates the cross product of this vector with another vector.

Examples

let (v1, v2) = (Vec3::<i32>::from_slice(&[2, 3, 4]), Vec3::<i32>::from_slice(&[5, 6, 7]));
assert_eq!(*v1.cross(v2).as_ref(), [-3, 6, -3]);

Trait Implementations

impl<T: Copy + NumAssign> From<Matrix<T, 2, 1>> for Vec3<T>

fn from(v: Vec2<T>) -> Self

Augments a Vec2 into a Vec3 The resulting Vec3 contains the given Vec2 with z = 1.

Examples

let v = Vec3::from(Vec2::<i32>::from_slice(&[2, 3]));
assert_eq!(*v.as_ref(), [2, 3, 1]);

impl<T: Copy + NumAssign> From<Matrix<T, 4, 1>> for Vec3<T>

fn from(v: Vec4<T>) -> Self

Creates a Vec3 from the (x, y, z) of a Vec4

Examples

let v = Vec3::from(Vec4::<i32>::from_slice(&[2, 3, 4, 1]));
assert_eq!(*v.as_ref(), [2, 3, 4]);

impl<T: Copy + NumAssign> From<Quaternion<T>> for Vec3<T>

fn from(q: Quaternion<T>) -> Self

Creates a Vec3 from a Quaternion by dropping the w component.

Examples

let v = Vec3::from(Quaternion::<i32>::from_slice(&[2, 3, 4, 5]));
assert_eq!(*v.as_ref(), [2, 3, 4]);
