I am getting a List of Points from the user clicking on the screen.
And I want to draw a polygon based on this points. The problem is that the user might not be clicking in the right order (no intersecting segments) to form a correct polygon, therefor I’m looking for a code snippet which would sort that List and arrange the points in the right order to form a good polygon…
Thanks!
picture = BAD POLY!

If you want to “wrap” the points in a polygon, you can use any number convex hull finding algorithms.
