# ARMeshAnchor

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

## Declaration

```swift
class ARMeshAnchor
```

## Overview

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.
