classification
A general characterization of what kind of real-world surface the plane anchor represents.
Declaration
@property (nonatomic, assign, readonly) ARPlaneClassification classification;Discussion
On supported devices, ARKit automatically attempts to characterize each detected plane, describing it as a real-world surface such as a wall, floor, or table. You can then use this information to enhance the realism of your AR experience; for example, by placing certain virtual content only on floors.
Plane classification can take longer than plane detection, and ARKit reports classifications only for planes where it has a high confidence in the result. Use this property together with the classificationStatus property to keep track of ARKit’s classification process:
If ARKit is still working to classify a plane, the classification is ARPlaneClassificationNone and the status is ARPlaneClassificationStatusUndetermined.
If ARKit cannot characterize a plane with high confidence, the classification is ARPlaneClassificationNone and the status is ARPlaneClassificationStatusUnknown.
Plane classification is available only on iPhone XS, iPhone XS Max, and iPhone XR. Before using classification results, check the isClassificationSupported class property to make sure you’re on a supported device.
