public sealed class ARPlane : ARTrackable<BoundedPlane, ARPlane>Remarks
Generated by the ARPlaneManager when an AR device detects a plane in the environment.
Properties
alignment
The alignment of this plane.
Declaration
public PlaneAlignment alignment { get; }Property Value
| Type | Description |
|---|---|

| NativeArray<Vector2> |
center
The 3D center point, in Unity world space.
Declaration
public Vector3 center { get; }Property Value
| Type | Description |
|---|---|
| Vector3 |
centerInPlaneSpace
The 2D center point, in plane space
Declaration
public Vector2 centerInPlaneSpace { get; }Property Value

|---|---|
| Vector2 |
classification
The classification of this plane.
Declaration
public PlaneClassification classification { get; }Property Value

Remarks
The data pointed to by this member is implementation defined. The lifetime of the pointed to object is also implementation defined, but should be valid at least until the next ARSession update.
normal
