Cannot figure out a workaround for INFINITE LOOP while unifying polygons

[Brandon10x15]

So basically I have a bunch of overlapping circles, which Im transforming to Polygons, checking for any intersecting polygons, and adding all of the polygon coordinates to an array, and then it should unify all of the polygons into one. Here's what I have so far

Here is the area that is being tested to merge.

	let polygon = new Polygon(intersecting[0]); 

	let polygonEdges = [];
	polygon.edges.forEach(edge => { polygonEdges.push([edge.shape.ps.x, edge.shape.ps.y]); });
	console.log(polygonEdges);

	// const m = new Flatten.Matrix().scale(1e6, 1e6);
	// polygon = polygon.transform(m);

	let ind = -1;
	for await (const points of intersecting) {
		ind++;
		if (ind !== 0) {

			let newPolygon = new Polygon(points);

			polygonEdges = [];
			newPolygon.edges.forEach(edge => { polygonEdges.push([edge.shape.ps.x, edge.shape.ps.y]); });
			console.log(polygonEdges);

			//newPolygon = newPolygon.transform(m);
			if ([...polygon.faces][0].orientation() != [...newPolygon.faces][0].orientation()) {
				newPolygon = newPolygon.reverse();
			}

			polygon = unify(polygon, newPolygon); // INFINITE LOOP error here
		} 
	}

	polygonEdges = [];
	polygon.edges.forEach(edge => { polygonEdges.push([edge.shape.ps.x, edge.shape.ps.y]); });
	console.log(polygonEdges);

The error (line 336 is the line that calls unify())

I have reviewed all of the old issues for this infinite loop but have not been able to find a workaround

[DeveloperUX]

We're running into a similar issue with the intersect function. Try transforming the polygons before and after you call unify. Scale the polygons up and then rotate them. call unify then unscale and unrotate them.

Encountering this as well – would've loved to use the library if not for infinite loops!

Hi, @Brandon10x15 ,

I tried you data and this is what I got:

I assume this is not what you planned.
Maybe you can give me your "bunch of overlapping circles", I will test on it.
In general library supposed to support boolean operations on circles as well.

@DeveloperUX , @max-vogler ,
Please give me your examples of data, I want to test them too
