Mengonfigurasi batasan peta dan kamera

Contoh kode berikut menunjukkan cara menggunakan CameraRestriction untuk membatasi batas geografis kamera dan nilai ketinggian, arah, dan kemiringan kamera. Untuk menggunakan contoh kode ini, ikuti petunjuk di Penyiapan dan Menambahkan peta 3D ke aplikasi Anda untuk menyiapkan project Android Studio dengan peta 3D dasar. Kemudian, tambahkan kode berikut ke file MainActivity.kt:

// Add imports and define constants

import com.google.android.gms.maps3d.model.latLngAltitude
import com.google.android.gms.maps3d.model.latLngBounds
import com.google.android.gms.maps3d.model.polygonOptions
