simdLocalFront
The unit vector SceneKit treats as “forward” in local space for all nodes.
Declaration
class var simdLocalFront: simd_float3 { get }Discussion
The “forward” direction of a node affects cameras and directional lighting attached to a node, as well as relative orientation and movement effects such as simdLook(at:), SCNLookAtConstraint, and SCNBillboardConstraint.
This vector is always (0, 0, -1) for all nodes, but you can use this class property when it’s convenient to refer to directions symbolically.
