# SCNRenderingAPI.openGLES2

Use the OpenGL ES 2.0 API for SceneKit rendering in iOS.

## Declaration

```swift
case openGLES2
```

## Discussion

Discussion This option is available on all iOS devices supporting SceneKit. If you request the Metal rendering API for an SCNView object on a device that does not support Metal, SceneKit falls back to the OpenGL ES 2.0 API.
