# upAxis

An SCNVector3 structure specifying the orientation of the scene.

## Declaration

```swift
static let upAxis: SCNScene.Attribute
```

## Discussion

Discussion The SCNVector3structure (in an NSValue object) may be present in scenes loaded from scene files produced using external tools, but has no effect on SceneKit’s processing of the scene. Use this vector when combining elements from different scenes so that they appear in their expected orientation.
