To create a new spatial anchor, simply add this component to any GameObject. The transform of the GameObject is used to create a new spatial anchor in the Oculus Runtime. Afterwards, the GameObject's transform will be updated automatically. The creation operation is asynchronous, and, if it fails, this component will be destroyed.

To load previously saved anchors and bind them to an OVRSpatialAnchor, see LoadUnboundAnchorsAsync(IEnumerable<Guid>,List<UnboundAnchor>,Action<List<UnboundAnchor>,int>).

Member Enumerations

Enumeration OperationResult

Possible results of operations related to anchor sharing.

Success	Operation succeeded.
Failure	Operation failed.
Failure_DataIsInvalid	Invalid data.
Failure_SpaceCloudStorageDisabled	Saving anchors to cloud storage is not permitted by the user.
Failure_SpaceMappingInsufficient	The user was able to download the anchors, but the device was unable to localize itself in the spatial data received from the sharing device.
Failure_SpaceLocalizationFailed	The user was able to download the anchors, but the device was unable to localize them.
Failure_SpaceNetworkTimeout	Network operation timed out.
Failure_SpaceNetworkRequestFailed	Network operation failed.

Properties

OVRAnchor _anchor[Get]

Guid Uuid[Get]

The UUID associated with the spatial anchor.

UUIDs persist across sessions. If you load a persisted anchor, you can use the UUID to identify it.

bool Created[Get]

Checks whether the spatial anchor is created.

Creation is asynchronous and may take several frames. If creation fails, the component is destroyed.

bool PendingCreation[Get]

Checks whether the spatial anchor is pending creation.

bool Localized[Get]

Checks whether the spatial anchor is localized.

When you create a new spatial anchor, it may take a few frames before it is localized. Once localized, its transform updates automatically.

OVRSpace Space[Get]

The space associated with the spatial anchor.

NOTE: This property is obsolete. This class provides all spatial anchor functionality and it should not be necessary to use this low-level handle directly. See SaveAsync(), ShareAsync(OVRSpaceUser), and EraseAsync().The OVRSpace represents the runtime instance of the spatial anchor and will change across different sessions.

Events

Action< OperationResult > OnLocalize

Event that is dispatched when the localization process finishes.

Static Member Functions

static OVRTask< OperationResult > ShareAsync

( IEnumerable< OVRSpatialAnchor > anchors,

IEnumerable< OVRSpaceUser > users )

The users will be able to download, localize, and share the specified anchors.This method is asynchronous. Use the returned OVRTask<TResult> to monitor completion.This operation fully succeeds or fails, which means, either all anchors are successfully shared or the operation fails.

Parameters

anchors

The collection of anchors to share.

users

An array of Oculus users to share these anchors with.

Returns

A task that can be used to track the completion of the sharing operation.

Exceptions

ArgumentNullException

Thrown if anchors is null.

ArgumentNullException

Thrown if users is null.

static OVRTask< OVRResult< OVRAnchor.SaveResult > > SaveAnchorsAsync

( IEnumerable< OVRSpatialAnchor > anchors )

Saves a collection of anchors.

This method is asynchronous; use the returned OVRTask<TResult> to be notified of completion. When saved, the OVRSpatialAnchor can be loaded by a different session. Use LoadUnboundAnchorsAsync(IEnumerable<Guid>,List<UnboundAnchor>,Action<List<UnboundAnchor>,int>) to load some or all OVRSpatialAnchor at a future time.This operation fully succeeds or fails; that is, either all anchors are successfully saved, or the operation fails.

Parameters

anchors

The anchors to save (up to 32).

Returns

An awaitable OVRTask<TResult> representing the asynchronous save operation.

Exceptions

ArgumentNullException

Thrown if anchors is null.

See Also

SaveAnchorAsync

Exceptions

ArgumentException

Thrown if anchors contains more than 32 anchors.

static OVRTask< OVRResult< OVRAnchor.EraseResult > > EraseAnchorsAsync

( IEnumerable< OVRSpatialAnchor > anchors,

IEnumerable< Guid > uuids )

Erase a collection of anchors from persistent storage.

This operation is asynchronous. Use the returned OVRTask<TResult> to track the result of the asynchronous operation.The total number of anchors (anchors and uuids ) may not exceed 32.

Parameters

anchors

(Optional) The anchors to erase

uuids

(Optional) The UUIDs to erase

Returns

An awaitable OVRTask<TResult> representing the asynchronous erase operation.

Exceptions

ArgumentException

Thrown if anchors and uuids are both null.

EraseAnchorAsync

Exceptions

ArgumentException

static OVRTask< OVRResult< List< UnboundAnchor >, OVRAnchor.FetchResult > > LoadUnboundAnchorsAsync

( IEnumerable< Guid > uuids,

List< UnboundAnchor > unboundAnchors,

Action< List< UnboundAnchor >, int > onIncrementalResultsAvailable )

Loads up to 50 unbound anchors with specified UUIDs.

An UnboundAnchor is an anchor that exists, but that isn't managed by an OVRSpatialAnchor. Use this method to load a collection of anchors by UUID that haven't already been bound to an OVRSpatialAnchor.In order to be loaded, the anchor must have previously been persisted, e.g., with SaveAnchorsAsync.NOTE: This method will only process the first 50 UUIDs provided by uuids .This method is asynchronous. The returned OVRTask<TResult> completes when all results are available. However, anchors may be loaded in batches. To be notified as the results of individual batches are loaded, provide an onIncrementalResultsAvailable callback. The callback accepts two parameters:

(List\<UnboundAnchor\> unboundAnchors, int startingIndex)

unboundAnchors is a reference to the unboundAnchors parameter.

startingIndex is the index into unboundAnchors which contains the first newly loaded anchor in this batch.

Before the task completes, it is undefined behavior to access unboundAnchors outside of onIncrementalResultsAvailable invocations.Note that if you bind an UnboundAnchor in the onIncrementalResultsAvailable callback, that same anchor will no longer be present in the unboundAnchors provided to future incremental results, or after the task completes. That is, an UnboundAnchor is removed from the list of unboundAnchors once it is bound.unboundAnchors is the buffer used to store the results. This allows you to reuse the same buffer between subsequent calls. The list is cleared before any anchors are added to it.

Parameters

uuids

The UUIDs of the anchors to load.

unboundAnchors

The buffer to store the resulting unbound anchors into.

onIncrementalResultsAvailable

An optional callback that is invoked whenever a new batch of unbound anchors has been loaded.

Returns

A new OVRTask<TResult> that completes when the loading operation completes.

Exceptions

ArgumentNullException

Thrown if uuids is null.

ArgumentNullException

Thrown if unboundAnchors is null.

static OVRTask< OVRResult< List< UnboundAnchor >, OperationResult > > LoadUnboundSharedAnchorsAsync

( IEnumerable< Guid > uuids,

List< UnboundAnchor > unboundAnchors )

Load anchors that have been shared with you.

Use this method to load spatial anchors that have been shared with you by another user.This method requires access to Meta servers to query for shared anchors. This method can fail in a few ways:

The device cannot reach Meta servers, e.g., because there is no internet access (see OperationResult.Failure_SpaceNetworkRequestFailed)

The user has denied the "Share Point Cloud Data" device permission (see OperationResult.Failure_SpaceCloudStorageDisabled)

The application has not declared "Shared Spatial Anchor Support" (OVRManager > Quest Features > General > Shared Spatial Anchor Support)

To load other types of anchors, use LoadUnboundAnchorsAsync(IEnumerable<Guid>,List<UnboundAnchor>,Action<List<UnboundAnchor>,int>).

Parameters

uuids

The set of anchor UUIDs to load

unboundAnchors

A buffer to store the loaded anchors. This container is cleared before being populated.

Returns

Returns an awaitable task-like object that can be used to track completion of the load operation.

Exceptions

ArgumentNullException

Thrown if uuids is null.

ArgumentNullException

Thrown if unboundAnchors is null.
