Struct XRTrackedImage

Contains low-level data for a tracked image in the environment.

Namespace: UnityEngine.XR.ARSubsystems

Syntax

public struct XRTrackedImage : ITrackable, IEquatable<XRTrackedImage>

Constructors

XRTrackedImage(TrackableId, Guid, Pose, Vector2, TrackingState, IntPtr)

Constructs an XRTrackedImage.

Declaration

public XRTrackedImage(TrackableId trackableId, Guid sourceImageId, Pose pose, Vector2 size, TrackingState trackingState, IntPtr nativePtr)

Parameters

Type	Name	Description
TrackableId	trackableId	The TrackableId associated with this tracked image.
Guid	sourceImageId	A GUID associated with the source image.
Pose	pose	The Pose associated with the detected image.
Vector2	size	The size (i.e., dimensions) of the detected image.
TrackingState	trackingState	The TrackingState of the detected image.
IntPtr	nativePtr	A native pointer associated with the detected image.

Properties

defaultValue

Generates a XRTrackedImage populated with default values.

Declaration

public static XRTrackedImage defaultValue { get; }

Property Value

Type	Description
XRTrackedImage

nativePtr

A native pointer associated with this tracked image. The data pointed to by this pointer is implementation-defined. While its lifetime is also implementation-defined, it should be valid at least until the next call to GetChanges(Allocator).

Declaration

public IntPtr nativePtr { get; }

Property Value

Type	Description
IntPtr

Implements

ITrackable.nativePtr

pose

The Pose associated with this tracked image.

Declaration

public Pose pose { get; }

Property Value

Type	Description
Pose

Implements

ITrackable.pose

size

The size (i.e., dimensions) of this tracked image.

Declaration

public Vector2 size { get; }

Property Value

Type	Description
Vector2

sourceImageId

The GUID associated with the source image.

Declaration

public Guid sourceImageId { get; }

Property Value

Type	Description
Guid

trackableId

The TrackableId associated with this tracked image.

Declaration

public TrackableId trackableId { get; }

Property Value

Type	Description
TrackableId

Implements

ITrackable.trackableId

trackingState

The TrackingState associated with this tracked image.

Declaration

public TrackingState trackingState { get; }

Property Value

Type	Description
TrackingState

Implements

ITrackable.trackingState

Methods

Equals(Object)

Tests for equality.

Declaration

public override bool Equals(object obj)

Parameters

Type	Name	Description
Object	obj	The object to compare against.

Returns

Type	Description
Boolean	True if obj is of type XRTrackedImage and Equals(XRTrackedImage) also returns true; otherwise false.

Overrides

ValueType.Equals(Object)

Equals(XRTrackedImage)

Tests for equality.

Declaration

public bool Equals(XRTrackedImage other)

Parameters

Type	Name	Description
XRTrackedImage	other	The other XRTrackedImage to compare against.

Returns

Type	Description
Boolean	True if every field in other is equal to this XRTrackedImage, otherwise false.

GetHashCode()

Generates a hash suitable for use with containers like HashSet and Dictionary.

Declaration

public override int GetHashCode()

Returns

Type	Description
Int32	A hash code generated from this object's fields.

Overrides

ValueType.GetHashCode()

Operators

Equality(XRTrackedImage, XRTrackedImage)

Tests for equality. Same as Equals(XRTrackedImage).

Declaration

public static bool operator ==(XRTrackedImage lhs, XRTrackedImage rhs)

Parameters

Type	Name	Description
XRTrackedImage	lhs	The left-hand side of the comparison.
XRTrackedImage	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	True if lhs is equal to rhs, otherwise false.

Inequality(XRTrackedImage, XRTrackedImage)

Tests for inequality. Same as !Equals(XRTrackedImage).

Declaration

public static bool operator !=(XRTrackedImage lhs, XRTrackedImage rhs)

Parameters

Type	Name	Description
XRTrackedImage	lhs	The left-hand side of the comparison.
XRTrackedImage	rhs	The right-hand side of the comparison.

Returns

Type	Description
Boolean	True if lhs is not equal to rhs, otherwise false.
