Struct UnitDisc 

pub struct UnitDisc;

Samples uniformly from the unit disc in two dimensions.

Implemented via rejection sampling.

For a distribution that samples only from the circumference of the unit disc, see UnitCircle.

For a similar distribution in three dimensions, see UnitBall.

Plot

The following plot shows the unit disc. This distribution samples individual points from the entire area of the disc.

Example

use rand_distr::{UnitDisc, Distribution};

let v: [f64; 2] = UnitDisc.sample(&mut rand::rng());
println!("{:?} is from the unit Disc.", v)
