Enum Values

public static final CameraConfig.FacingDirection BACK

BACK

public static final CameraConfig.FacingDirection BACK

Back-facing (world) camera (away from the user).

Available on all ARCore supported devices.

When used as a camera filter, via CameraConfigFilter.setFacingDirection(CameraConfig.FacingDirection), filters for camera configs that use a back-facing (world) camera.

public static final CameraConfig.FacingDirection FRONT

FRONT

public static final CameraConfig.FacingDirection FRONT

Front-facing (selfie) camera (toward the user).

See ARCore supported devices for available camera configs by device.

To limit distribution of your app to only devices that have a front-facing camera, use uses-feature with android.hardware.camera.

When used as a camera filter, via CameraConfigFilter.setFacingDirection(CameraConfig.FacingDirection), filters for camera configs that use a front-facing (selfie) camera.

To create a session using the front-facing (selfie) camera, use Session.setCameraConfig(CameraConfig) to set a front-facing (selfie) camera config retrieved from Session.getSupportedCameraConfigs(CameraConfigFilter).

When the front camera is selected, ARCore's behavior changes in the following ways:

• The display will be mirrored. Specifically, Camera.getProjectionMatrix(float[], int, float, float) will include a horizontal flip in the generated projection matrix and APIs that reason about things in screen space such as Frame.transformCoordinates2d(Coordinates2d, float[], Coordinates2d, float[]) will mirror screen coordinates. Open GL apps should consider using glFrontFace to render mirrored assets without changing their winding direction.
• Camera.getTrackingState() will always return TrackingState.PAUSED.
• All forms of Frame.hitTest() will always return an empty list.
• Camera.getDisplayOrientedPose() will always return an identity pose.
• Session.createAnchor(Pose) will always throw NotTrackingException.
• Planes will never be detected.
• Session.configure(Config) will throw if the supplied configuration requests Cloud Anchors or Augmented Images.
