# SCNLayer

A Core Animation layer that renders a SceneKit scene as its content.

```
class SCNLayer
```

## Overview

Use this class to integrate 3D content rendered by SceneKit into a user interface composed of Core Animation layers. To provide content for the layer, assign an [`SCNScene`](/documentation/SceneKit/SCNScene) object to its [`scene`](/documentation/SceneKit/SCNLayer/scene) property.

Most of the methods and properties you use for working with a SceneKit layer are defined by the [`SCNSceneRenderer`](/documentation/SceneKit/SCNSceneRenderer) protocol.

## Topics

### Specifying a Scene

[`scene`](/documentation/SceneKit/SCNLayer/scene)

The scene to be displayed in the layer.
