The 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. dying light 2 developer
