Configure map and camera restrictions

The following code sample demonstrates how to use CameraRestriction to restrict both the geographical boundaries of the camera and the values of the camera's altitude, heading, and tilt. To use this code sample, follow the instructions in Setup and Add a 3D map to your app to set up your Android Studio project with a basic 3D map. Then, add the following code to the MainActivity.kt file:

// Add imports and define constants
import com.google.android.gms.maps3d.model.AltitudeMode
import com.google.android.gms.maps3d.model.LatLngAltitude
import com.google.android.gms.maps3d.model.cameraRestriction
import com.google.android.gms.maps3d.model.latLngAltitude
import com.google.android.gms.maps3d.model.latLngBounds
import com.google.android.gms.maps3d.model.polygonOptions

    northEastLng = NYC_NORTH_EAST_LNG
    southWestLat = NYC_SOUTH_WEST_LAT

}

// Define the restrictions
val nycCameraRestriction = cameraRestriction {
  minAltitude = MIN_ALTITUDE_NYC_METERS
  maxAltitude = MAX_ALTITUDE_NYC_METERS
