# simdLocalUp

The direction SceneKit treats as “up” in local space for all nodes.

## Declaration

```swift
class var simdLocalUp: simd_float3 { get }
```

## Discussion

Discussion The “up” direction of a node affects cameras attached to a node, as well as relative orientation and movement effects such as simdLook(at:), SCNLookAtConstraint, and SCNBillboardConstraint. This vector is always (0, 1, 0) for all nodes, but you can use this class property when it’s convenient to refer to directions symbolically.
