Struct flow_sdk::algorithms::secp256k1::rand::distributions::UnitSphereSurface

pub struct UnitSphereSurface;

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

Implemented via a method by Marsaglia¹.

Example

use rand::distributions::{UnitSphereSurface, Distribution};

let sphere = UnitSphereSurface::new();
let v = sphere.sample(&mut rand::thread_rng());
println!("{:?} is from the unit sphere surface.", v)
