### Efficiently Get Regions Around a Triangle

Source: https://github.com/redblobgames/mapgen4/blob/main/dual-mesh/README.org

This snippet shows how to efficiently get the regions around a triangle by providing an output array. It also demonstrates the convenience of returning the array directly, which allocates a new one.

```js
let out_r = [];
mesh.r_around_t(t, out_r);
// output written into out_r
```

```js
let out_r = mesh.r_around_t(t);
// output allocates a new array and returns it
```

### Create Mesh with Poisson Disk Sampling

Source: https://github.com/redblobgames/mapgen4/blob/main/dual-mesh/README.org

Shows how to create a mesh using Poisson disk sampling for point generation, with an option to set boundary spacing.

```js
let Poisson = require('poisson-disk-sampling');
let mesh = new MeshBuilder({boundarySpacing: 75})
    .addPoisson(Poisson, 75)
    .create();
```

### Create Mesh from Points

Source: https://github.com/redblobgames/mapgen4/blob/main/dual-mesh/README.org

Demonstrates how to create a mesh by adding an array of points using the MeshBuilder.

```js
let mesh = new MeshBuilder()
    .addPoints(array_of_points)
    .create();
```
