I’m putting a collection of points into a Polygon shape like so: 

<Polygon Points="{Binding vertices, Converter={StaticResource pointCollectionConverter}}" Stretch="None" Stroke="Black" StrokeThickness="2" Fill="#7EBB9A" />

However, on relatively complex inputs, the polygon doesn’t come out like I’d expect it to. For example, here is an output:

enter image description here

The problem is that this polygon has two interesections that should not be there. It should have these edges instead(in Red):

I’m not how to fix this, and if not I guess I have to resort to drawing it manually.
