XRAnchor3D
An anchor point in AR space.
XRAnchor3D.swift:16class XRAnchor3D
The XRAnchor3D
point is a spatial node that maps a real world location identified by the AR platform to a position within the game world. For example, as long as plane detection in ARKit is on, ARKit will identify and update the position of planes (tables, floors, etc) and create anchors for them.
This node is mapped to one of the anchors through its unique ID. When you receive a signal that a new anchor is available, you should add this node to your scene for that anchor. You can predefine nodes and set the ID; the nodes will simply remain on 0,0,0 until a plane is recognized.
Keep in mind that, as long as plane detection is enabled, the size, placing and orientation of an anchor will be updated as the detection logic learns more about the real world out there especially if only part of the surface is in view.

Conformances
protocol CustomStringConvertible
A type with a customized textual representation.
protocol Equatable
A type that can be compared for value equality.
protocol Hashable
A type that can be hashed into a
Hasher
to produce an integer hash value.protocol Identifiable<ID>
A class of types whose instances hold the value of an entity with stable identity.
protocol VariantRepresentable
Types that conform to VariantRepresentable can be stored directly in
Variant
with no conversion. These include all of the Variant types from Godot (for exampleGString
,Rect
,Plane
), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.protocol VariantStorable
Types that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.

Instance members
func getPlane(
) -> Plane Returns a plane aligned with our anchor; handy for intersection testing.
func getSize(
) -> Vector3 Returns the estimated size of the plane that was detected. Say when the anchor relates to a table in the real world, this is the estimated size of the surface of that table.
