Struct VectorsOnUnitDisk 

pub struct VectorsOnUnitDisk;

A uniform distribution of 2-vectors inside the (closed) unit disk.

Trait Implementations

impl Clone for VectorsOnUnitDisk

fn clone(&self) -> VectorsOnUnitDisk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorsOnUnitDisk

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

Formats the value using the given formatter.

impl Default for VectorsOnUnitDisk

fn default() -> VectorsOnUnitDisk

Returns the “default value” for a type.

impl Distrib for VectorsOnUnitDisk

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

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

Example

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

let vec = VectorsOnUnitDisk.sample(rng);
assert!(vec.len_sqr() <= 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.
