Struct rand_distr::UnitSphere

source ·
pub struct UnitSphere;
Expand description

Samples uniformly from the surface of the unit sphere in three dimensions.

Implemented via a method by Marsaglia1.

Example

use rand_distr::{UnitSphere, Distribution};

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