# simdWorldUp

The “up” (+Y) direction vector relative to the node, expressed in world space.

```
var simdWorldUp: simd_float3 { get }
```

## Discussion

Reading this property is equivalent to reading the [`simdLocalUp`](/documentation/SceneKit/SCNNode/simdLocalUp) class property and using the [`simdConvertVector(_:to:)`](/documentation/SceneKit/SCNNode/simdConvertVector(_:to:)) or [`simdConvertVector(_:from:)`](/documentation/SceneKit/SCNNode/simdConvertVector(_:from:)) method to convert that vector from the node’s local coordinate space to the scene’s world coordinate space.
