The new demo app for the lidar scanner uses RealityKit and the user is able to visualize meshes detected by the scanner:https://developer.apple.com/documentation/arkit/world_tracking/visualizing_and_interacting_with_a_reconstructed_sceneThe meshes are visualized using 'showSceneUnderstanding' as a debug option:arView.debugOptions.insert(.showSceneUnderstanding)You can also occlude virtual content by accessing the sceneUnderstanding:arView.environment.sceneUnderstanding.options.insert(.occlusion)I am trying to recreate these features using SceneKit but so far i've had no success. It looks like 'sceneUnderstading' doesn't seem to exist in SceneKit. There doesn't seem to be any documentation on this.Any help would be appreciated.Thanks.
