Member Function Documentation

abstract Anchor CreateMidAirAnchor ( string  name,
Vector3  position,
Quaternion  rotation 
)
pure virtual

Creates an Anchor Trackable for MidAir using the Transform of the pose (position/rotation) where it should be anchored.

When using VUFORIA_SENSOR_FUSION, Anchors created with this method are not guaranteed to receive any further position updates after the device tracker recovers from a limited tracking state.

Parameters
nameThe logical name of the anchor. This must be unique among all created anchors.
transformThe transform of the pose at which the anchor will be created
Returns
Anchor that can be used to configure an AnchorBehaviour
abstract Anchor CreatePlaneAnchor ( string  name,
HitTestResult  hitTestResult 
)
pure virtual

Creates an Anchor Trackable on a Plane using the HitTestResult of a previous SmartTerrain.HitTest of the (position/rotation) where it should be anchored.

Parameters
nameThe logical name of the anchor. This must be unique among all created anchors.
hitTestResultThe HitTestResult containing the pose at which the anchor will be created on a plane
Returns
Anchor that can be used to configure an AnchorBehaviour
abstract void RegisterAnchorRemovedCallback ( Action< Anchor onAnchorRemovedAction)
pure virtual

Register for the event of when an Anchor is removed and no longer being tracked, for example after pause/resume in some cases

Parameters
onAnchorRemovedAction
abstract bool Reset ( )
pure virtual

Reset the tracker On some platforms a new world coordinate system may be created with the device's current position and orientation as the origin. On some platforms the underlying Vuforia Fusion provider may also be reset. Any internal data will be destroyed. All created anchors will be destroyed. It is recommended to call ResetAnchors() afterwards.

Returns
true if the positional device tracker correctly reset

abstract void ResetAnchors ( )
pure virtual

Reset all anchors in the current scene. By default, the ContentPositioningBehaviour will delete all Anchors it has created. If the ContentPositioningBehaviour is not use, the anchors must be dealt with explicitly by registering to the Callbacks 'RegisterAnchorRemovedCallback' and 'UnregisterAnchorRemovedCallback'

abstract void UnregisterAnchorRemovedCallback ( Action< Anchor onAnchorRemovedAction)
pure virtual

Unregister for the event of when an Anchor is removed and no longer being tracked, for example after pause/resume in some cases

Parameters
onAnchorRemovedAction
