Instance Property

simdWorldFront

The "forward" (-Z) direction vector relative to the node, expressed in world space.

Declaration

@property(readonly, nonatomic) simd_float3 simdWorldFront;

Discussion

Reading this property is equivalent to reading the simdLocalFront class property and using the simdConvertVector:toNode: or simdConvertVector:fromNode: method to convert that vector from the node's local coordinate space to the scene's world coordinate space.
