Consider what happens when you take three of the points and form the triangle with them and the fourth point happens to be in the interior of that triangle. E.g. as pictured here. $\endgroup$ –

One important concept related to this is winding, which defines the relative order in which the vertex points of a polygon are listed.Winding can be either clockwise (CW) or counter-clockwise (anti-clockwise) … grasshopper clueThe algorithm works on star-shaped polygons when the centre point is in the kernel. Convex polygons are star shaped and their kernel is the whole polygon, so clockwise sorting is guanateed to work for them. You can use clockwise sorting for the second polygon, too, if you find a way to move the centre to the part where the bars of the T cross. grasshopper club zurich vs fc sionWebA ring is a connected sequence of four or more points that form a closed, non-self-intersecting loop.
