Trackable A Trackable is something that ARCore can track and that Anchors can be attached to. 


Anchor Describes a fixed location and orientation in the real world. 
ArCoreApk Static methods for managing the status of ARCore on the device. 
ArImage This class exposes ArImage obtained from NDK AImage as Image interface. 
AugmentedFace Describes a face detected by ARCore and provides methods to access additional center and face region poses as well as face mesh related data. 
AugmentedImage Describes the current best knowledge of a real-world augmented image. 
AugmentedImageDatabase Database containing a list of images to be detected and tracked by ARCore. 
Camera Provides information about the camera that is used to capture images. 
CameraConfig Provides details of a camera configuration such as size of the CPU image and GPU texture. 
CameraConfigFilter Allows the application to select the camera config filters it needs to enable/disable so that it can obtain the list of camera configs that are supported on the device camera. 
CameraIntrinsics Provides information about the physical characteristics of the device camera, for the camera image (CPU) or texture (GPU). 
Config Holds settings that are used to configure the session. 
DepthPoint On supported devices, represents a depth image based HitResult returned by Frame.hitTest(float, float)
Frame Captures the state and changes to the AR system from a call to Session.update()
HitResult Defines an intersection between a ray and estimated real-world geometry. 
ImageFormat Image formats produced by ARCore. 
ImageMetadata Provides access to metadata from the camera image capture result. 
InstantPlacementPoint Trackable Instant Placement point returned by Frame.hitTestInstantPlacement(float, float, float)
LightEstimate Holds information about the estimated lighting of the real scene. 
Plane Describes the current best knowledge of a real-world planar surface. 
Point Represents a point in space that ARCore is tracking. 
PointCloud Contains a set of observed 3D points and confidence values. 
Pose Represents an immutable rigid transformation from one coordinate space to another. 
RecordingConfig Configuration related to session recording. 
Session Manages AR system state and handles the session lifecycle. 
SharedCamera The SharedCamera class allows the app to share control of the camera with ARCore and obtain image readers and surfaces for rendering. 
Track Configuration of a Track for recording data on session recording. 
TrackData Data that was recorded to a track.

Session.Feature Fundamental session features that can be requested using Session.Session(Context, Set)
Session.FeatureMapQuality Indicates the quality of the visual features seen by ARCore in the preceding few seconds from a given camera Pose
TrackingFailureReason Describes possible AR tracking failure reasons. 
TrackingState Describes the tracking state of the Trackable.
