simdWorldUp
The “up” (+Y) direction vector relative to the node, expressed in world space.
Declaration
var simdWorldUp: simd_float3 { get }Discussion
Reading this property is equivalent to reading the simdLocalUp class property and using the simdConvertVector(_:to:) or simdConvertVector(_:from:) method to convert that vector from the node’s local coordinate space to the scene’s world coordinate space.
