# PolygonCoordinates

PolygonCoordinates[poly]

gives a list of coordinates in the polygon poly.

# Details

• PolygonCoordinates is also known as polygon vertex coordinates.
• PolygonCoordinates is defined by the canonicalization performed in CanonicalizePolygon.
• PolygonCoordinates gives a list of coordinates {p1,p2,}.
• For a polygon with self-intersections, the resulting coordinate list will also include intersection points.
• For a polygon defined with repeated coordinates, the resulting coordinate list removes duplicate coordinates.
