# ARConfiguration.SceneReconstruction

Options that enable ARKit to detect the shape of the physical environment.

```
struct SceneReconstruction
```

## Overview

When you set one of the these values onto a world-tracking configuration’s [`sceneReconstruction`](/documentation/ARKit/ARWorldTrackingConfiguration/sceneReconstruction) property, ARKit provides you with a mesh that models the real-world surrounding the user.

## Topics

### Modeling the Environment

[`init(rawValue:)`](/documentation/ARKit/ARConfiguration/SceneReconstruction/init(rawValue:))

Initializes a scene-reconstruction object.

[`mesh`](/documentation/ARKit/ARConfiguration/SceneReconstruction/mesh)

A polygonal mesh approximation of the physical environment.

[`meshWithClassification`](/documentation/ARKit/ARConfiguration/SceneReconstruction/meshWithClassification)

An approximate shape of the physical environment, including classification of the real-world objects within it.

[`ARSceneReconstructionNone`](/documentation/ARKit/ARSceneReconstruction/ARSceneReconstructionNone)

Disables the scene reconstruction feature.
