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;
