Struct UnitSphere 

pub struct UnitSphere;

A uniform distribution of unit 3-vectors.

Trait Implementations

impl Clone for UnitSphere

fn clone(&self) -> UnitSphere

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UnitSphere

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

Formats the value using the given formatter.

impl Default for UnitSphere

fn default() -> UnitSphere

Returns the “default value” for a type.

impl Distrib for UnitSphere

Available on crate feature fp only.

fn sample(&self, rng: &mut DefaultRng) -> Vec3

Returns a unit 3-vector uniformly sampled from the unit sphere.

Example

use retrofire_core::assert_approx_eq;
use retrofire_core::math::rand::*;
let rng = &mut DefaultRng::default();

let vec = UnitSphere.sample(rng);
assert_approx_eq!(vec.len_sqr(), 1.0);

type Sample = Vector<[f32; 3], Real<3>>

The type of the elements of the sample space of Self, also called “outcomes”.

fn samples(&self, rng: &mut DefaultRng) -> impl Iterator<Item = Self::Sample>

Returns an iterator that yields samples from self indefinitely.
