Hi @BrokenCode,

I’m not really familiar with Lee Byron’s “mesh” library but here is my two cents:

- `getRegions()` only work with Voronoi objects
- the “Triangulate” library seems more appropriate in your case

You just need to:

- download it [here](http://n.clavaud.free.fr/processing/triangulate/triangulate-20100628.zip)

- import it in your sketch

- put all the points (PVector) you want to triangulate in an array list (let’s call it `plist`)

- call the `triangulate` method on that list: -\> `triangles = Triangulate.triangulate(plist)`

- display the triangles with the `beginShape(TRIANGLES)` function and fill them as you like:

```auto
beginShape(TRIANGLES)
for t in triangles:
    fill(random(255), random(255), random(255))
    vertex(t.p1.x, t.p1.y)
    vertex(t.p2.x, t.p2.y)
    vertex(t.p3.x, t.p3.y)
endShape()

```
