WebJan 8, 2024 · I understand that this is because of how sorted () works, that is guaranteed to be stable (items with the same key appears in the original order) and that the within () method obviously returns false if the two geometry are apart from each other, but I was expecting that at least the "relative order" would be kept (that is, to always have [c, c, …
WebAug 20, 2024 · Set of unordered vertices. If the vertices are not ordered clockwise or anti-clockwise, then calculating the area can be a little tricky. That means, before calling the polygon_area(points), we need to sort the points clockwise or anti-clockwise.
