poisson2d is a fork of poisson, a library for generating N-dimensional Poisson disk samplings. It provides a mint API for compatibility with most computer graphics linear algebra libraries, but can only generate 2D samplings. If you're interested in higher-dimensional samplings, see poisson.

Specifically, poisson2d can generate a sampling of points in [0, 1)² where:

• Sample points fill the space uniformly.
• Sample points stay a given minimum distance apart.

This is equivalent to uniformly filling a unit square with non-overlapping disks of equal radius, where the radius is half the minimum distance:

Due to their blue noise properties, Poisson disk samplings can be used for object placement in procedural texture/world generation, digital stippling, sampling in rendering, or (re)meshing.

Works with mint 0.5 and rand 0.7.

use poisson2d::{Builder, Type, algorithm};
use rand::FromEntropy;
use rand::rngs::SmallRng;

fn main() {
    let poisson =
        Builder::with_radius(0.1, Type::Normal)
            .build(SmallRng::from_entropy(), algorithm::Ebeida);
    println!("{:?}", poisson.generate());
}
