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
Gets the normal to this plane in world space.
Declaration

| Vector2 |
subsumedBy
The ARPlane which has subsumed this plane, or null
if this plane has not been subsumed.
Declaration

vertexChangedThreshold
The largest value by which a plane's vertex may change before the mesh is regenerated. Units are in meters.
Declaration
public float vertexChangedThreshold { get; set; }Property Value
| Type | Description |
|---|---|
| Single |
Events
boundaryChanged
Invoked when any vertex in the plane's boundary changes by more than vertexChangedThreshold.
Declaration
