בדוגמת הקוד הבאה אפשר לראות איך מוסיפים מצולע תלת-ממדי וממקמים אותו במרחב תלת-ממדי באמצעות הפעלת השיטה addPolygon. כדי להשתמש בדוגמת הקוד הזו, צריך לפעול לפי ההוראות במאמרים הגדרה והוספת מפה תלת-ממדית לאפליקציה כדי להגדיר את פרויקט Android Studio עם מפה תלת-ממדית בסיסית. אחר כך מוסיפים את הקוד הבא לקובץ MainActivity.kt:
