XRAnchor3D

XRAnchor3D inherits XREntity3D: select Tracker, then Pose, and parent the Entity directly under XROrigin3D. It enables no AR detection and does not guarantee platform-created anchor trackers. The data provider determines names and availability.

GetPlane builds an infinite plane from local Position and local Transform Y. This is parent space, not world space. The following executed helper adds the origin transform once:

using System;
using Reckfell;

public static class AnchorPlane
{
    // Infinite geometric plane only: no tracking-validity or detected-area claim.
    public static Plane ToWorld(XRAnchor3D anchor)
    {
        ArgumentNullException.ThrowIfNull(anchor);
        if (!anchor.IsInsideTree() || anchor.GetParent() is not XROrigin3D origin)
            throw new ArgumentException("Expected an anchor directly under an in-tree XROrigin3D.");
        return origin.GlobalTransform * anchor.GetPlane();
    }
}

Plane contains no bounds, collision geometry or proof of a detected surface. Check the current pose separately before interaction. GetSize currently remains zero even after pose updates: no extent-population path is implemented. Do not use it as floor area or collider dimensions.

Local geometry, the world helper, synthetic tracker transforms and zero size were checked. No real AR surface, platform spatial anchoring, anchor persistence or boundary detection was tested. Tracking state: XREntity3D.
