# SCNRenderer

A renderer for displaying a SceneKit scene in an existing Metal workflow or OpenGL context.

## Declaration

```swift
class SCNRenderer
```

## Overview

Overview Use this class when you want to add content rendered by SceneKit to an app that already renders other content by using Metal, OpenGL, or OpenGL ES directly. To provide content for a SceneKit renderer, assign a SCNScene object to its scene property. For additional important methods and properties for working with SceneKit renderers, see SCNSceneRenderer.
