Instance Property


The bounding region of the scene to which light probes are being added.



var boundingBox: MDLAxisAlignedBoundingBox { get set }


When you call the MDLAsset placeLightProbes(withDensity:heuristic:using:) method to automatically distribute light probes in a scene, Model I/O reads this property to ask your code which regions should be evaluated for light probe placement.
