WindingPolygon

WindingPolygon[{p1, p2, ..., pn}] gives a polygon representing all points for which the closed contour p1, p2, ..., pn, p1 winds around at least once.

• WindingPolygon[{{p11, p12, ...}, {p21, p22, ...}, ...}] gives a polygon from the closed contours p11, p12, ... and p21, p22, ....
• WindingPolygon[..., "wrule"] uses the specified winding rule "wrule" to define the polygon.

This function creates polygons from self-intersecting contours using winding number rules.

Examples

WindingPolygon[{{0, 0}, {1, 0}, {1, 1}, {0, 1}}]

(* Star polygon with winding *)
WindingPolygon[CirclePoints[5, 2]]
