TryGetAssetTrackingData
Attempts to get the pose of a VPS asset's origin, in AR session space.

---

## Declaration

public bool TryGetAssetTrackingData(out XRVps2AssetTrackingData trackingData, string assetId = null)

#### Summary

Attempts to get the pose of a VPS asset's origin, in AR session space.

#### Remarks

Polling drives tracking: the first call for an asset starts tracking its origin,
    so keep polling while this returns false. Data is only served while the
    asset is fully tracked; false also covers lapsed tracking and an asset id
    not yet known to the session (e.g. a TryLocalize for its
    site is still in flight). The pose is in AR session space, like
    TryCreateAnchor and TryGetPose; for Unity world-space
    placement, prefer the ARVps2AssetManager trackables, which follow
    the asset origin automatically.

#### Returns

true if tracking data is available; otherwise false.

### Parameters

| Name | Type | Summary |
| --- | --- | --- |
| trackingData | XRVps2AssetTrackingData | Receives the asset's tracking data on success. |
| assetId | string | The identifier of the VPS map asset, or null for the asset the device is currently localized to (see LocalizedAsset). Only null selects the localized asset; an empty id returns false. |
