Information about the position and orientation of a real-world flat surface detected in a world-tracking AR session.
SDK
Framework
When you run a world-tracking AR session whose plane option is enabled, the session automatically adds to its list of anchors an ARPlane object for each flat surface ARKit detects with the back-facing camera. Each plane anchor provides information about the estimated position and shape of the surface.
var alignment: ARPlaneThe general orientation of the detected plane with respect to gravity.
enum ARPlaneValues describing possible general orientations of a detected plane with respect to gravity.
var geometry: ARPlaneA coarse triangle mesh representing the general shape of the detected plane.
class ARPlaneA 3D mesh describing the shape of a detected plane in world-tracking AR sessions.
class ARSCNPlaneA SceneKit representation of the 2D shape of a plane, for use with plane detection results in an AR session.
var center: simdThe center point of the plane relative to its anchor position.
var extent: simdThe estimated width and length of the detected plane.

class ARWorldA configuration that uses the back-facing camera, tracks a device's orientation and position, and detects real-world surfaces, and known images or objects.
class AREnvironmentAn object that provides environmental lighting information for a specific area of space in a world-tracking AR session.
