# smoothedSceneDepth An option that provides the distance from the device to real-world objects, averaged across several frames. ``` static var smoothedSceneDepth: ARConfiguration.FrameSemantics { get } ``` ## Discussion Enable this option on a world-tracking configuration ([`ARWorldTrackingConfiguration`](/documentation/ARKit/ARWorldTrackingConfiguration)) to instruct ARKit to provide your app with the distance between the user’s device and the real-world objects pictured in the frame’s [`capturedImage`](/documentation/ARKit/ARFrame/capturedImage). ARKit samples this distance using the LiDAR scanner and provides the results through the [`smoothedSceneDepth`](/documentation/ARKit/ARFrame/smoothedSceneDepth) property on the session’s [`currentFrame`](/documentation/ARKit/ARSession/currentFrame). To minimize the difference in LiDAR readings across frames, ARKit processes the data as an average. The averaged readings reduce flickering to create a smoother motion effect when depicting objects with depth, as demonstrated in [Creating a fog effect using scene depth](/documentation/ARKit/creating-a-fog-effect-using-scene-depth). Alternatively, to access a discrete LiDAR reading at the instant the framework creates the current frame, use [`sceneDepth`](/documentation/ARKit/ARFrame/sceneDepth). ARKit supports scene depth only on LiDAR-capable devices, so call [`supportsFrameSemantics(_:)`](/documentation/ARKit/ARConfiguration/supportsFrameSemantics(_:)) to ensure device support before attempting to enable scene depth. --- Copyright © 2026 Apple Inc.
