Implementations

impl Rng

pub fn new(seed: u64) -> Self

pub fn next_u64(&mut self) -> u64

pub fn next_f64(&mut self) -> f64

Uniform float in [0, 1).

pub fn next_range(&mut self, lo: f64, hi: f64) -> f64

Uniform float in [lo, hi).

pub fn next_direction2<S: Scalar>(&mut self) -> Vector2<S>

A random direction, uniformly distributed on the unit circle.

pub fn next_direction3<S: Scalar>(&mut self) -> Vector3<S>

A random direction, uniformly distributed on the unit sphere (Archimedes’ cylindrical projection: uniform z, uniform angle).
