Elementare Polygone (Vielecke)
Bei einem gegebenen Satz von Punkten können Sie einfache Polygone erstellen und grundlegende geometrische Mengen wie Bereiche berechnen. Für komplexere Polygone oder Zugriff auf mehr geometrische Informationen erstellen Sie ein polyshape
-Objekt. Verwenden Sie dann Objektfunktionen zum Ändern, Abfragen und Visualisieren des Polygons oder des Polygonsatzes.
