# ARMeshAnchor

An anchor for a physical object that ARKit detects and recreates virtually using a polygonal mesh.

```
class ARMeshAnchor
```

## Overview

ARKit subdivides the reconstructed, real-world scene surrounding the user into mesh anchors.

Mesh anchors constantly update their data as ARKit refines its understanding of the real world. Although ARKit updates a mesh to reflect a change in the physical environment (such as when a person pulls out a chair), the mesh’s subsequent change is not intended to reflect in real time.

## Topics

### Accessing the Mesh

[`geometry`](/documentation/ARKit/ARMeshAnchor/geometry)

3D information about the mesh such as its shape and classifications.

[`ARMeshGeometry`](/documentation/ARKit/ARMeshGeometry)

Mesh information stored in an efficient, array-based format.
