نمونه کد زیر نحوه اضافه کردن چند ضلعی سه بعدی و قرار دادن آن در فضای سه بعدی را با فراخوانی متد addPolygon نشان می دهد. برای استفاده از این نمونه کد، دستورالعملهای موجود در راهاندازی را دنبال کنید و نقشه سه بعدی را به برنامه خود اضافه کنید تا پروژه Android Studio خود را با یک نقشه سه بعدی اولیه تنظیم کنید. سپس کد زیر را به فایل MainActivity.kt اضافه کنید:
