# Vps2AssetTrackingData Source: https://www.nianticspatial.com/docs/api/swift/NSDK.struct-Vps2AssetTrackingData/ Vps2AssetTrackingData --- ## Declaration struct Vps2AssetTrackingData ## Summary Pose of a VPS asset's origin in the device's AR tracking space. Content authored in the asset's coordinate space is placed with `assetToTrackingTransform`. Only served while the asset is fully tracked; see `NSDKVps2Session/assetTrackingData(assetId:)`. --- ## Properties | Name | Type | Summary | | --- | --- | --- | | let assetId | String | The identifier of the asset. | | let assetToTrackingTransform | simd_float4x4 | Transform from the asset's coordinate space to the AR session'sworld space. | | let confidence | Float | Confidence in the transform, from 0 (none) to 1 (full). | | var debugDescription | String | A textual representation of this instance, suitable for debugging.Calling this property directly is discouraged. Instead, convert aninstance of any type to a string by using the `String(reflecting:)`initializer. This initializer works with any type, and uses the custom`debugDescription` property for types that conform to`CustomDebugStringConvertible`: struct Point: CustomDebugStringConvertible { let x: Int, y: Int var debugDescription: String { return "((x), (y))" } } let p = Point(x: 21, y: 30) let s = String(reflecting: p) print(s) // Prints "(21, 30)"The conversion of `p` to a string in the assignment to `s` uses the`Point` type's `debugDescription` property. | | let siteId | String | The identifier of the site the asset belongs to. | | let timestampMs | UInt64 | Timestamp of the camera frame the transform was last updated from,in monotonic milliseconds. | --- ## Relationships conforms to: Swift.CustomDebugStringConvertible
