L'exemple de code suivant montre comment ajouter un polygone 3D et le positionner dans l'espace 3D en appelant la méthode addPolygon. Pour utiliser cet exemple de code, suivez les instructions de Configuration et Ajouter une carte 3D à votre application pour configurer votre projet Android Studio avec une carte 3D de base. Ajoutez ensuite le code suivant au fichier MainActivity.kt :
