با تنظیم ویژگی altitudeMode روی یکی از مقادیر زیر می توانید ارتفاع نشانگر را تنظیم کنید:
ABSOLUTE
RELATIVE_TO_GROUND
CLAMP_TO_GROUND
RELATIVE_TO_MESH
نمونه کد زیر نحوه استفاده از هر یک از روش ها را 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:
