```

```swift
convenience init(context: CGLContextObj?, options: [AnyHashable : Any]? = nil)
```

## Parameters

- `context`: An OpenGL rendering context: either a doc://com.apple.documentation/documentation/AppKit/NSOpenGLContext/cglContextObj reference (in macOS) or an doc://com.apple.documentation/documentation/OpenGLES/EAGLContext object (in iOS).

## Discussion

Discussion Use this initializer to create a SceneKit renderer that draws into OpenGL context your app already uses to draw other content. To tell SceneKit to render your content, call the SCNRenderer or SCNRenderer method.
