localUp
The direction SceneKit treats as “up” in local space for all nodes.
Declaration
class var localUp: SCNVector3 { get }Discussion
The “up” direction of a node affects cameras attached to a node, as well as relative orientation and movement effects such as look(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.
