ReferenceFrame

NameSpace: MagicLeap

Contains information necessary to report on XRAnchor s.

Public Fields

anchor

Get the reference frame as a refernce point


public XRAnchor anchor { get; set; }


anchorPose

Compute the pose of the anchor.


public Pose anchorPose { get; set; }


cfuid

The UID of the closest coordinate frame


public Native.MagicLeapNativeBindings.MLCoordinateFrameUID cfuid { get; set; }

TypeDescription
Native.MagicLeapNativeBindings.MLCoordinateFrameUIDA unique identifier which represents a coordinate frame. The unique identifier is comprised of two values.

coordinateFrame

The pose of the coordinate frame used as the origin when calculating the anchorPose.


public Pose coordinateFrame { get; set; }


trackableId

The anchor's trackable id.


public TrackableId trackableId { get; set; }


trackingState

The tracking state associated with the anchor


public TrackingState trackingState { get; set; }


Public Methods

void ComputeDelta

public void ComputeDelta(
Pose pose
)

Parameters

TypeNameDescription
Posepose

unsafe TrackableId GenerateTrackableId

public static unsafe TrackableId GenerateTrackableId()

ReferenceFrame

public ReferenceFrame(
Cinfo cinfo
)

Parameters

TypeNameDescription
CinfocinfoInformation necessary to construct a reference frame

void SetCoordinateFrame

Sets a new coordinate frame. This is different from simply setting the coordinateFrame. This method causes the anchor to be computed relative to a different coordinate frame entirely.

public void SetCoordinateFrame(
Native.MagicLeapNativeBindings.MLCoordinateFrameUID cfuid,
Pose coordinateFrame
)

Parameters

TypeNameDescription
Native.MagicLeapNativeBindings.MLCoordinateFrameUIDcfuidThe UID of the new coordinate frame
PosecoordinateFrameThe pose of the new coordinate frame

bool SetTrackingState

Sets the tracking state and returns true if the state changed.

public bool SetTrackingState(
TrackingState trackingState
)

Parameters

TypeNameDescription
TrackingStatetrackingStateThe new tracking state

Returns: true if the tracking state changed.


Public Attributes

m_AnchorFromCoordinateFrame

A pose which describes the delta beteen the anchor and the closest MLCoordinateFrame.


public Pose m_AnchorFromCoordinateFrame;
