Finding the medial axis or skeleton of the disappeared portion when offsetting inside a polygon

[YITWEE]

When offsetting certain narrow sections of a polygon by a significant distance, it may result in disconnected portions. In such cases, is there a way to calculate the medial axis or skeleton of the disconnected portion?

Hi, This is an issue I struggled with for a about a year.
I wrote a method called GetInsetWithMedian which creates something near the median, and cuts the median lines that are within the inset, and leaves the median lines outside of it.
To find the median I used Voronoi Diagram generated with Boost. It was alot of work. I can share the source code for it privatly.

Not using the Clipper2 library. Sorry.
