# ARSCNPlaneGeometry

A SceneKit representation of the 2D shape of a plane, for use with plane detection results in an AR session.

## Declaration

```swift
class ARSCNPlaneGeometry
```

## Overview

Overview ARSCNPlaneGeometry is a subclass of SCNGeometry that wraps the mesh data provided by the ARPlaneGeometry class. You can use ARSCNPlaneGeometry to visualize the plane shape estimates provided by ARKit in a SceneKit view. important: ARSCNPlaneGeometry is available only in SceneKit views or renderers that use Metal. This class is not supported for OpenGL-based SceneKit rendering. As your AR session continues to run, ARKit provides refined estimates of a detected plane’s 2D shape. Use the update(from:) method to incorporate those refinements into the plane’s SceneKit representation.
