Struct UnitCircle 

pub struct UnitCircle;

A uniform distribution of unit 2-vectors.

Trait Implementations

impl Clone for UnitCircle

fn clone(&self) -> UnitCircle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnitCircle

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

Formats the value using the given formatter.

impl Distrib for UnitCircle

Available on crate feature fp only.

fn sample(&self, rng: &mut DefaultRng) -> Vec2

Returns a unit 2-vector uniformly sampled from the unit circle.

Example

use retrofire_core::math::{ApproxEq, rand::*};
let rng = &mut DefaultRng::default();

let vec = UnitCircle.sample(rng);
assert!(vec.len_sqr().approx_eq(&1.0));

type Sample = Vector<[f32; 2], Real<2>>

The type of the elements of the sample space of Self, also called “outcomes”.

fn samples(&self, rng: &mut DefaultRng) -> impl Iterator<Item = Self::Sample>

Returns an iterator that yields samples from self indefinitely.
