Defines the interface for a trackable. A trackable represents anything that can be detected and tracked in the physical environment.

Namespace: UnityEngine.XR.ARSubsystems

Assembly: Unity.XR.ARSubsystems.dll

Syntax

public interface ITrackable

Properties

nativePtr

The native pointer associated with this trackable.

Declaration

IntPtr nativePtr { get; }

Property Value

Type	Description
IntPtr	The native pointer.

Remarks

The data pointed to by this pointer is defined by the provider plug-in implementation. Refer to the provider documentation for each platform your app supports to learn more about the value of this pointer on your target platform(s).

pose

The Pose, in session space, associated with this trackable.

Declaration

Pose pose { get; }

Property Value

Type	Description
Pose	The pose.

Examples

Some ITrackable implementations are MonoBehaviours, and you can use the Transform component of their GameObjects to access the position and rotation of a trackable in Unity world space. For other trackables without associated GameObjects, you can convert a session-space pose to Unity world space if needed by using the example code below, assuming the XR Origin has a uniform scale of (1, 1, 1):

var origin = FindAnyObjectByType<XROrigin>().transform;
var originPose = new Pose(origin.position, origin.rotation);
var worldSpacePose = pose.GetTransformedBy(xrOriginPose);

trackableId

The TrackableId associated with this trackable.

Declaration

TrackableId trackableId { get; }

Property Value

Type	Description
TrackableId	The TrackableId.

trackingState

The TrackingState associated with this trackable.

Declaration

TrackingState trackingState { get; }

Property Value

Type	Description
TrackingState	The TrackingState.
