# 1.4.0 Update

I have just released [v1.4.0](https://github.com/micycle1/PGS/releases/tag/1.4.0) of PGS and I’m once again presenting some of the new functionality here:

This library is incredible, thank you! Previous releases included a javadoc jar which I used to create a PGS docset for [Dash](https://kapeli.com/dash) via their [javadocset](https://github.com/Kapeli/javadocset) tool. Would it be possible to get the updated javadocs as well?

Thanks again!

Thanks!  
I’ve now added the javadoc jar to the release on Github.

# 2.0 Update

I’ve recently released 2.0, which takes the codebase to Java 17.

With the new update, PGS is now finally available on Processing’s contribution manager as “_Geometry Suite for Processing_”.

![image](https://github.com/user-attachments/assets/4da45ff8-8b67-4bdf-91de-589dbb518ed1)

A few examples of new features:

Hi hi 🙂 Thank you for PGS Michael! 🙂

I’ve been having fun with it from OPENRNDR and created things like this:

> **[aBe (@hamoid@genart.social)](https://genart.social/@hamoid/114321812972321461)**
>
> Attached: 1 image
> 
> The program no longer crashes and the fix was simpler than I thought. 
> 
> Instead of comparing rounded doubles (what a silly idea) I did the proper thing, which is abs(a - b) \< epsilon. A lot of times 🙂 Takes maybe half second to...

I’m writing because I just tried the Sponge feature and I’m getting unexpected results, and I’m not sure if I’m using it wrong, if something is wrong on the OPENRNDR side, or it’s something else.

 ![2025-10-18_16-07](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/a/f/af9d8a30abc6707d6c0f7ae75a15d92c303b6515.png)

Is it expected that `createSponge` returns a PShape of type `PShape.PATH` ? I was expecting it to have children for each hole…

Also… is this a good place to ask? Or better on GitHub?

Thanks!

Hey, please you’re using it!  
Github is generally better, but we can stay here for now.

The type and childcount are expected. Holes are defined via Processing contours. Might there be a PShape rendering issue with OPENRNDR that doesn’t properly account for Processing’s strange way of defining holes? ([i.e](https://github.com/micycle1/PGS/blob/c93cb28532b748a2b42a84dc8e4fe8f95d3987fb/src/main/java/micycle/pgs/PGS_Conversion.java#L1926))

This is what I get for those args (albeit a different width/height):

Thank you for the useful link! Sounds like it will help me figure out the issue 🙏

The issue was in the conversion from `PShape` to `ShapeContour` 😌

Hi! In the PGS readme in GitHub (down at the moment) I see an image labeled “Multiplicatively Weighted Voronoi”.

When I try this program:

```processing
import micycle.pgs.*;
import java.util.List;

PShape design;
void setup() {
  size(600, 600);
  List<PVector> points = PGS_PointSet.random(50.0, 50.0, width - 50.0, height - 50.0, 50);
  println(points.size());
  double[] bounds = { 30.0d, 30.0d, width - 30.0d, height - 30.0d };
  design = PGS_Voronoi.multiplicativelyWeightedVoronoi(points, bounds, true);
}
void draw() {
  background(0);
  shape(design);
}

```

it produces this image

but it doesn’t have the nice curves I see in the readme:

![mwvd](https://canada1.discourse-cdn.com/flex036/uploads/processingfoundation1/original/3X/d/1/d1bdd89c24cb3167e9c71586e3626372f42bdcdb.gif)

Do you have any curves to spare? 🙂

Thank you 🙂

The MWVD uses the .z value of each point for the multiplicative weight of the site.

Since all your weights are equal (0), you effectively get a regular voronoi diagram.

(`PGS_PointSet.applyRandomWeights()` might be of use).

It’s actually a rather effective technique to create organic looking tessellations, particularly in negative space:

That’s an impressive list of new methods! Congratulations on the release.

Trying to run the examples, I did notice a few that didn’t seem to run in 2.2.

So far I had issues with:

`triangulate` → `The function pigmentMix(int, int, float) does not exist.`

and

`voronoiCutout` → `The function shapeIntersection(PShape, PShape) does not exist.`

I have not tried all of them so there might be more.

Ah right, I did check that some examples were working and took that to be good enough, but clearly not enough.

I’ll amend those, thanks.
