# simdWorldOrientation

The node’s orientation relative to the scene’s world coordinate space.

```
var simdWorldOrientation: simd_quatf { get set }
```

## Discussion

This quaternion isolates the rotational aspect of the node’s [`simdWorldTransform`](/documentation/SceneKit/SCNNode/simdWorldTransform) matrix, which in turn is the conversion of the node’s [`simdTransform`](/documentation/SceneKit/SCNNode/simdTransform) from local space to the scene’s world coordinate space. That is, it expresses the difference in axis and angle of rotation between the node and the scene’s [`rootNode`](/documentation/SceneKit/SCNScene/rootNode).
