CameraPosition

Package: com.eegeo.mapapi.camera

Class which encapsulates a 3D camera position and orientation.

Fields

public final LatLng target

The coordinate of the interest point that the camera is pointing at.

public final double targetElevation

The elevation of the interest point, in meters. The property is interpreted differently, depending on targetElevationMode.

public final ElevationMode targetElevationMode

An enumerated value indicating whether targetElevation is specified as a height above terrain, or an absolute altitude above sea level.

public final String targetIndoorMapId

For a camera with interest point on an indoor map, the string identifier of the indoor map; else, an empty string.

public final int targetIndoorMapFloorId

For a camera with interest point on an indoor map, the identifier of an indoor map floor on which the target interest point lies.

public final double zoom

The zoom level, in the range 0 to 26.

public final double tilt

The angle formed at the target coordinate from the camera direction to the vertical, in degrees.

public final double bearing

The camera bearing, in degrees clockwise from north.

class CameraPosition.Builder

Builds a CameraPosition.

Constructors

Builder()

Creates an empty builder.

Builder(CameraPosition previous)

Creates an builder initialised to the values of the supplied CameraPosition

Methods

CameraPosition.Builder target(double latitude, double longitude)

Sets the target point of the camera.

Returns: Updated CameraPosition.Builder object.

Type argument Description
double latitude Latitude in degrees.
double longitude Longitude in degrees.

CameraPosition.Builder target(double latitude, double longitude, double altitude)

Sets the target point of the camera.

Returns: Updated CameraPosition.Builder object.

Type argument Description
double latitude Latitude in degrees.
double longitude Longitude in degrees.
double altitude Altitude in meters.

CameraPosition.Builder target(LatLng latLon)

Sets the target point of the camera.

Returns: Updated CameraPosition.Builder object.

Type argument Description
LatLng latLon Target point.

CameraPosition.Builder target(LatLngAlt latLonAlt)

Sets the target point of the camera.

Returns: Updated CameraPosition.Builder object.

Type argument Description
LatLngAlt latLonAlt Target point.

CameraPosition.Builder elevation(double elevation)

Sets the targetElevation for the CameraPosition. The default targetElevation is 0. Note that this is an experimental field - values other than 0 may have unexpected effects on camera control

Returns: Updated CameraPosition.Builder object.

Type argument Description
double elevation The elevation, in meters.

CameraPosition.Builder elevationMode(ElevationMode elevationMode)

Sets the targetElevationMode for the CameraPosition. The default targetElevationMode is ElevationMode.HeightAboveGround. Note that this is an experimental field - values other than ElevationMode.HeightAboveGround may have unexpected effects on camera control

Returns: Updated CameraPosition.Builder object.

Type argument Description
ElevationMode elevationMode The ElevationMode used to interpret the targetElevation.

CameraPosition.Builder indoor(String indoorMapId, int indoorMapFloorId)

Sets the indoor map properties for the CameraPosition target. If this method is not called, the builder is initialised to create a CameraPosition with its interest point on an outdoor map.

Returns: Updated CameraPosition.Builder object.

Type argument Description
String indoorMapId The identifier of the indoor map of the camera target interest point.
int indoorMapFloorId The identifier of the indoor map floor of the camera target interest point.

CameraPosition.Builder zoom(double zoom)

Sets the camera zoom.

Returns: Updated CameraPosition.Builder object.

Type argument Description
double zoom The new zoom value.

CameraPosition.Builder tilt(double tilt)

Sets the tilt of the camera.

Returns: Updated CameraPosition.Builder object.

Type argument Description
double tilt Camera tilt in degrees. Tilt is an offset from the earth normal, so a tilt of 0 means the camera looks straight down at the earth. The SDK will clamp the requested tilt to be within limits dependent on altitude.

CameraPosition.Builder bearing(double bearing)

Sets the orientation of the camera in the earth tangent plane, in degrees clockwise from north.

Returns: Updated CameraPosition.Builder object.

Type argument Description
double bearing The direction that the camera is facing, in degrees clockwise from north.

CameraPosition build()

Builds a CameraPosition object.

Returns: The final CameraPosition object.
