 EGoogleARCoreAugmentedFaceMode

Describes the possible modes for Augmented Face detection.

 EGoogleARCoreCameraFacing

Describes the orientation of the selected camera relative to the device display.

 EGoogleARCoreCoordinates2DType

2d coordinate systems referenced by ARCore.

Properties
`Image`	ARCore normalized pass-through camera image(for CPU usage) space with top-left (0.0f, 0.0f) and bottom-right(1.0f, 1.0f).
`Texture`	ARCore normalized pass-through camera texture(for GPU usage) space with top-left (0.0f, 0.0f) and bottom-right(1.0f, 1.0f).
`Viewport`	UE4 normalized viewport space with top-left(0,0f ,0.0f) and bottom-right(1.0f, 1.0f)

 EGoogleARCoreFunctionStatus

Describes the status of most ARCore functions.

Properties
`Fatal`	Function failed due to Fatal error.
`IllegalState`	Function failed due to it is invoked at an illegal or inappropriate time.
`InvalidType`	Function failed due to the function augment has invalid type.
`NotAvailable`	Function failed due to ARCore session hasn't started or the requested resource isn't available yet.
`NotTracking`	Function failed due to ARCore session isn't in tracking state.
`ResourceExhausted`	Function failed due to the requested resource is exhausted.
`SessionPaused`	Function failed due to the session isn't running.
`Success`	Function returned successfully.
`Unknown`	Function failed with unknown reason.

 EGoogleARCoreLineTraceChannel

Describes which channel ARLineTrace will be performed on.

Properties
`AugmentedImage`	Trace against augmented images.
`FeaturePoint`	Trace against feature point cloud.
`FeaturePointWithSurfaceNormal`	Trace against feature point and attempt to estimate the normal of the surface centered around the trace hit point. Surface normal estimation is most likely to succeed on textured surfaces and with camera motion.
`InfinitePlane`	Trace against the infinite plane.
`PlaneUsingBoundaryPolygon`	Trace against the plane using its boundary polygon.
`PlaneUsingExtent`	Trace against the plane using its extent.

 EGoogleARCoreTrackingFailureReason

Describes the possible tracking failure reasons in ARCore.

Properties
`BadState`	Tracking lost due to bad internal state. Please try restarting the AR experience. This should be seen rarely, and should be reported to and fixed by ARCore team.
`ExcessiveMotion`	Tracking lost due to excessive motion. Please move device more slowly.
`InsufficientFeatures`	Tracking lost due to insufficient trackable features. Please move to area with more features, such as corners, objects, surfaces with texture. Avoid blank walls and surfaces without detail.
`InsufficientLight`	Tracking lost due to poor lighting conditions. Please move to a more brightly lit area
`None`	Tracking is working normally, or ARCore session is not currently running.

 EGoogleARCoreTrackingState

Describes the tracking state of the current ARCore session.

Properties
`NotTracking`	Tracking is temporary lost but could recover in the future.
`StoppedTracking`	Tracking is lost will not recover.
`Tracking`	Tracking is valid.
