impl Vec3

pub const ZERO: Self = _

a zero vector

pub const ONE: Self = _

pub fn extend(self, w: f32) -> Vec4

pub fn truncate(self) -> Vec2

pub fn splat(value: f32) -> Self

create a vector where x, y and z equals value.

pub fn length_squared(self) -> f32

pub fn length(self) -> f32

length of the vector.

pub fn distance_squared(self, other: Vec3) -> f32

distance between two vectors before being square rooted.

pub fn distance(self, other: Vec3) -> f32

distance between two vectors.

pub fn dot(self, other: Vec3) -> f32

get the dot product of 2 vectors. equal to the cosign of the angle between vectors.

pub fn cross(&self, other: Vec3) -> Vec3

get the cross product of 2 vectors. equal to the vector that is perpendicular to both input vectors. the output vector is not normalised.

use glium_types::vectors::{Vec3, vec3};
let x = vec3(1.0, 0.0, 0.0);
let y = vec3(0.0, 1.0, 0.0);
let z = vec3(0.0, 0.0, 1.0);
assert!(x.cross(y) == z);

pub fn scale(self, scalar: f32) -> Vec3

multiplies each value by the scalar.

pub fn normalise(self) -> Self

makes the length of the vector equal to 1. on fail returns vec3 of zeros

pub fn transform(self, matrix: &Mat3) -> Self

transforms vector by the matrix
