Struct rand_distr::UnitBall

pub struct UnitBall;

Samples uniformly from the unit ball (surface and interior) in three dimensions.

Implemented via rejection sampling.

Example

use rand_distr::{UnitBall, Distribution};

let v: [f64; 3] = UnitBall.sample(&mut rand::thread_rng());
println!("{:?} is from the unit ball.", v)

Trait Implementations

impl Clone for UnitBall

fn clone(&self) -> UnitBall

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for UnitBall

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

Formats the value using the given formatter.

impl<F: Float + SampleUniform> Distribution<[F; 3]> for UnitBall

fn sample<R: Rng + ?Sized>(&self, rng: &mut R) -> [F; 3]

Generate a random value of T, using rng as the source of randomness.

pub fn sample_iter<R>(self, rng: R) -> DistIter<Self, R, T> where
    R: Rng, 

Create an iterator that generates random values of T, using rng as the source of randomness.
