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: vector_float3The center point of the plane relative to its anchor position.
var extent: vector_float3The estimated width and length of the detected plane.
Create an app that runs an AR session and uses plane detection to place 3D content using SceneKit.
Follow best practices for visual feedback, gesture interactions, and realistic rendering in AR experiences.
class ARWorldA configuration that uses the back-facing camera, tracks a device's orientation and position, and detects real-world flat surfaces.
class AROrientationA configuration that uses the back-facing camera and tracks only a device's orientation.
