Use this method to get the pose of the anchor after it has been localized with LocalizeAsync.If the anchor is not localized, this method throws InvalidOperationException. If the anchor has been localized, but the pose cannot be retrieved (for example, because of a temporary tracking issue), then this method returns false, and you should try again later.

Parameters

pose

If this method returns true, then pose will contain the world space pose of the anchor. If this method returns false, pose is set to identity.

Returns

Returns true if the pose could be obtained, otherwise false.

Exceptions

InvalidOperationException

Thrown if the anchor is invalid, e.g., because it has been destroyed.

InvalidOperationException

Thrown if the anchor has not been localized.

OVRTask< bool > LocalizeAsync

( double timeout )

Localizes an anchor.

The delegate supplied to LoadUnboundAnchorsAsync(IEnumerable<Guid>,List<UnboundAnchor>,Action<List<UnboundAnchor>,int>) receives an array of unbound spatial anchors. You can choose whether to localize each one and be notified when localization completes.Upon successful localization, your delegate should instantiate an OVRSpatialAnchor, then bind the UnboundAnchor to the OVRSpatialAnchor by calling UnboundAnchor.BindTo. Once an UnboundAnchor is bound to an OVRSpatialAnchor, it cannot be used again; that is, it cannot be bound to multiple OVRSpatialAnchor components.

Parameters

timeout

The timeout, in seconds, to attempt localization, or zero to indicate no timeout.

Returns

Returns an OVRTask<bool> indicating the success of the localization.

Exceptions

InvalidOperationException

Thrown if the anchor does not support localization, e.g., because it is invalid.

void BindTo

( OVRSpatialAnchor spatialAnchor )

Binds an unbound anchor to an OVRSpatialAnchor component.

Use this to bind an unbound anchor to an OVRSpatialAnchor. After BindTo is used to bind an UnboundAnchor to an OVRSpatialAnchor, the UnboundAnchor is no longer valid; that is, it cannot be bound to another OVRSpatialAnchor.

Parameters

spatialAnchor

The component to which this unbound anchor should be bound. It should have been recently instantiated, ideally on the same frame as this call.

Exceptions

InvalidOperationException

Thrown if this UnboundAnchor does not refer to a valid anchor.

ArgumentNullException

Thrown if spatialAnchor is null.

ArgumentException

Thrown if an anchor is already bound to spatialAnchor .

ArgumentException

Thrown if spatialAnchor is pending creation (see OVRSpatialAnchor.PendingCreation).

InvalidOperationException

Thrown if this UnboundAnchor is already bound to an OVRSpatialAnchor.

void Localize

( Action< UnboundAnchor, bool > onComplete,

double timeout )

(Obsolete) Localizes an anchor.

The delegate supplied to OVRSpatialAnchor.LoadUnboundAnchors receives an array of unbound spatial anchors. You can choose whether to localize each one and be notified when localization completes.The onComplete delegate receives two arguments:

bool: Whether localization was successful
UnboundAnchor: The anchor to bind

Upon successful localization, your delegate should instantiate an OVRSpatialAnchor, then bind the UnboundAnchor to the OVRSpatialAnchor by calling UnboundAnchor.BindTo. Once an UnboundAnchor is bound to an OVRSpatialAnchor, it cannot be used again; that is, it cannot be bound to multiple OVRSpatialAnchor components. Deprecated

This method is obsolete. Use LocalizeAsync instead. To continue using the onComplete callback, use OVRTask<T>.ContinueWith on the returned task.

Parameters

onComplete

A delegate invoked when localization completes (which may fail). The delegate receives two arguments:
