+/// Entry point for the cross-platform augmented reality API.
+///
+/// AR sessions track the device's pose in the real world through the camera,
+/// detect surfaces, and composite virtual 3D content into the camera image.
+/// The typical flow: check `#isSupported()`, `#open(ARSessionOptions)` a
+/// session, add its `ARSession#createView()` to a form, then place content by
+/// hit testing taps against detected planes and hanging `ARNode`s on the
+/// resulting anchors.
+///
+/// **Permissions and dependencies**: simply referencing classes in this
+/// package causes the build pipeline to inject the camera permission, the
+/// `NSCameraUsageDescription` plist entry (iOS, override via the
+/// `ios.NSCameraUsageDescription` build hint) and the ARCore dependency
+/// (Android). Devices without AR support report `#isSupported()` false;
+/// always guard AR functionality behind that check.
+///

+/// if (AR.isSupported()) {

+/// Cross-platform augmented reality: world tracking, plane detection, hit
+/// testing, anchors, 3D content placement, light estimation, image tracking
+/// and face tracking, backed by ARKit on iOS and ARCore on Android.
+///
+/// Start at `AR`: check `AR#isSupported()` and per-feature
+/// `AR#getCapabilities()`, then `AR#open(ARSessionOptions)` a session and add
+/// its `ARSession#createView()` to a form. Place content by hit testing
+/// screen taps (`ARSession#hitTest(float, float)`), creating an `ARAnchor` at
+/// a hit and attaching an `ARNode` holding an `ARModel` (glTF or
+/// `com.codename1.gpu.Mesh` geometry).
+///
+/// **Coordinates**: world space is right-handed, in meters, with Y up and -Z
+/// forward from the initial camera direction - the convention shared by ARKit
+/// and ARCore. Poses are `ARPose` (translation + quaternion), convertible to
+/// `com.codename1.gpu.Matrix4` compatible matrices.
+///
+/// **Threading**: all listeners fire on the EDT and all getters reflect the
+/// latest delivered state. High-frequency refinements are coalesced.
+///
+/// **Permissions and dependencies**: referencing this package makes the build
+/// pipeline inject the camera permission and plist usage description plus the
+/// platform AR dependency into the application automatically; apps that do
+/// not use AR pay no cost. Devices without AR hardware report
+/// `AR#isSupported()` false, as do the simulator-less desktop targets - the
+/// Codename One simulator itself ships a simulated AR environment for

+/// Simulated AR backend for the Codename One simulator, modeled on the
+/// Android emulator's ARCore "virtual scene": the session runs against a
+/// virtual room whose floor and wall planes are "detected" shortly after the
+/// session opens, mimicking real AR startup. The AR view renders the room
+/// plus every anchored `ARNode` through the port's software 3D device, with
+/// the virtual device camera driven by the mouse (drag to look) and keyboard
+/// (WASD / arrow keys to move, Q / E for up / down).
+///
+/// The full core event pipeline - plane events, anchors, hit tests, image
+/// and face anchors, light estimates - flows through the same
+/// `ARImpl.EventSink` contract the native backends use, so application AR
+/// logic is debuggable in the simulator with breakpoints. The
+/// Simulate - AR Simulation window (`ARSimulation`) drives error states,
+/// lighting, image detection and face toggling.

+== Augmented Reality
+
+The `com.codename1.ar` package composites virtual 3D content into the live camera image: the session tracks the device's position in the real world, detects surfaces, recognizes registered images and faces, and keeps virtual objects locked to real-world positions as the user moves. It's backed by ARKit on iOS and by ARCore (Google Play Services for AR) on Android, behind one portable API.
+
+Referencing any class in the package is enough to wire the build: the class scanner injects the camera permission, the `NSCameraUsageDescription` plist entry (override the text with the `ios.NSCameraUsageDescription` build hint), links ARKit and SceneKit on iOS and adds the ARCore dependency plus the `com.google.ar.core` manifest entry on Android. Apps that never touch the package pay no size, permission or store-visibility cost. By default the Android manifest marks AR `optional` so the app still installs on devices without ARCore; set the `android.ar.required=true` build hint to make the app AR-only.
+
+[WARNING]
+====
+Always guard AR functionality behind `AR.isSupported()`. Older devices, tvOS, watchOS, desktop builds and browsers report `false`; feature-specific hardware such as face tracking is gated through `AR.getCapabilities()`.
+====
+
+=== Concepts
+
+[cols="1,3"]
+|===
+|Type |Role
+
+|`AR`
+|Static entry point: support and capability checks, permission request, session opening.
+
+|`ARSession`
+|The running AR experience. One session may be open at a time; it owns the view, the anchors and the detected planes, and delivers all events.
+
+|`ARView`
+|The component that renders the camera image composited with the anchored content. Add it to a form like any other component.
+
+|`ARPose`
+|An immutable position + rotation in world space: meters, right-handed, Y up, -Z forward from the initial camera direction. Converts to a `com.codename1.gpu.Matrix4` compatible matrix.
+
+|`ARPlane`
+|A detected real-world surface (floor, table, wall) that grows and refines as the session learns the environment.
+
+|`ARHitResult`
+|The intersection of a screen-point ray with real-world geometry; the bridge from a tap to a world position.
+
+|`ARAnchor`
+|A tracked fixed point in the real world. The attachment point for content; also delivered for recognized images (`ARImageAnchor`) and faces (`ARFaceAnchor`).
+
+|`ARNode` / `ARModel`
+|The content placed at an anchor: a small scene graph of nodes carrying glTF models or `com.codename1.gpu.Mesh` geometry.
+
+|`ARLightEstimate`
+|The real-world lighting estimate, polled per frame to shade content so it blends in.
+|===
+
+=== Getting started: Place a model on the floor
+
+The canonical AR loop is: open a session, show its view, wait for a plane, hit test a tap, anchor content at the hit.
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/ar/ArSnippets.java[tag=placeModel,indent=0]
+----
+
+`ARSessionOptions` configures the session before it opens: the tracking mode (`WORLD` or `FACE`), which plane orientations to detect, whether to estimate lighting, and the reference images to recognize. The defaults open a world tracking session with horizontal plane detection and light estimation, which suits the place-content-on-a-surface use case above.
+
+=== Plane detection
+
+Planes are delivered through `ARPlaneListener` as immutable snapshots: an `ADDED` event when a new surface is found, `UPDATED` snapshots (sharing the same `getId()`) as the surface grows, and `REMOVED` when a plane merges into another. `ARSession.getPlanes()` always reflects the latest snapshots.
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/ar/ArSnippets.java[tag=planeListener,indent=0]
+----
+
+The plane's local frame has X/Z spanning the surface and Y along the normal; `getCenterPose()` positions that frame in the world. `ARPlane.Type` distinguishes upward-facing horizontal surfaces (floors, tables), downward-facing ones (ceilings) and vertical surfaces (walls) - request vertical detection with `ARSessionOptions.planeDetection(ARPlaneDetection.HORIZONTAL_AND_VERTICAL)`.
+
+=== Hit testing and anchors
+
+`hitTest(xNorm, yNorm)` shoots a ray from a normalized view coordinate into the world and resolves - on the EDT - with the intersections ordered nearest first. Prefer `ARHitResult.createAnchor()` over `session.createAnchor(pose)` when placing on detected geometry: the platform can then anchor to the exact native raycast, which tracks better as the environment refines.
+
+Anchors survive tracking refinements: the session updates `getPose()` over time and reports the change through `ARAnchorListener`. Remove an anchor (and its content) with `detach()`. Content attaches through `setNode(ARNode)`:
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/ar/ArSnippets.java[tag=anchorContent,indent=0]
+----
+
+Node transforms are relative to the anchor, in meters. Nodes may nest (`addChild`), carry glTF assets (`ARModel.fromGltf`) or portable meshes (`ARModel.fromMesh`), and any mutation after attachment - position, rotation, scale, visibility, children - re-syncs the platform renderer automatically.
+
+=== Light estimation
+
+`session.getLightEstimate()` returns the latest estimate of the real-world lighting. It refreshes every frame without firing events, so poll it when rendering-relevant decisions are made. The ambient intensity is normalized so `1.0` means neutral indoor lighting; the color correction is a per-channel scale where `{1, 1, 1}` is neutral. Platform renderers already apply the estimate to anchored content; the API exposes it for custom logic such as prompting the user when the room is too dark.
+
+=== Image tracking
+
+Register printed images - posters, game boards, product labels - and the session anchors content to them when the camera sees them:
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/ar/ArSnippets.java[tag=imageTracking,indent=0]
+----
+
+The physical width matters: the platform uses it to estimate the image's distance, so measure the real print. The anchor pose is centered on the physical image with local X/Z spanning its surface.
+
+=== Face tracking
+
+Face tracking is a distinct session configuration using the front camera; open it with `ARSessionOptions.trackingMode(ARTrackingMode.FACE)` after checking `AR.getCapabilities().isFaceTrackingSupported()`. Detected faces arrive as `ARFaceAnchor`s through the anchor listener, carrying the head pose plus optional finer geometry:
+
+- `getRegionPose(ARFaceRegion)` returns the pose of a named region. Availability differs per platform (ARCore supplies the nose tip and forehead regions, ARKit supplies the eyes), which is why code must always handle a `null` region.
+- `getMeshVertices()` / `getMeshTriangles()` expose the tracked face mesh where the platform provides one, or `null` where it doesn't.
+
+=== Events and threading
+
+Every listener fires on the EDT and every getter reflects the state as of the events delivered so far, so AR code follows normal Codename One threading rules with no extra synchronization. High-frequency refinements (anchor and plane updates, camera pose, light estimate) are coalesced: a slow EDT sees the latest values rather than a backlog. This contrasts with the `com.codename1.gpu.Renderer` callbacks used by the VR API, which run on the render thread.
+
+=== The simulator and debugging
+
+The Codename One simulator ships a simulated AR backend modeled on the Android emulator's virtual scene, so the full AR loop is debuggable with breakpoints without a device. When a session opens, the simulator "detects" the floor (and, when requested, a wall) of a virtual room after a short startup delay, mimicking real AR initialization. The AR view renders the room and every anchored model; drive the virtual device camera with the mouse (drag to look around) and keyboard (`W`/`A`/`S`/`D` or the arrow keys to move, `Q`/`E` for up and down).
+
+image::img/ar-simulator-model.png[A model placed on the virtual room floor in the simulator,scaledwidth=30%]
+
+The Simulate menu's *AR Simulation* window drives the paths that are hard to reproduce on demand with real hardware: force degraded tracking states and failure reasons, change the light estimate, re-run plane detection, trigger recognition of a registered reference image, and toggle a simulated face anchor for `FACE` sessions.
+
+On devices, use the standard native tools: the generated Xcode project debugs the ARKit session and SceneKit scene directly (including Instruments), and Android Studio attaches to the Gradle project for ARCore logging. Note that Apple's iOS Simulator has no ARKit support - real ARKit behavior needs a physical device - while the Android emulator can run ARCore against its own virtual scene.
+
+=== Platform notes
+
+- *Dependencies*: injected automatically as described above. The ARCore dependency adds about 2 MB to Android binaries; iOS links the system ARKit/SceneKit frameworks at no size cost.
+- *Capabilities*: face tracking requires a capable front camera (a TrueDepth camera on iOS). Check `ARCapabilities` per feature rather than assuming.
+- *Face regions*: ARCore supplies `NOSE_TIP`, `FOREHEAD_LEFT` and `FOREHEAD_RIGHT`; ARKit supplies `LEFT_EYE` and `RIGHT_EYE`. Code that uses regions must handle a `null` region.
+- *ARCore installation*: on Android, Play Services for AR may need installing or updating; when `AR.open` triggers that flow it throws with a message saying to retry once installation completes.
+- *tvOS / watchOS*: AR compiles out entirely; `AR.isSupported()` reports `false`.

+== Virtual Reality and 360 Media
+
+The `com.codename1.vr` package renders application scenes in stereoscopic VR and displays 360-degree panoramas, built entirely on the portable `com.codename1.gpu` pipeline and the `com.codename1.sensors` motion sensors. There is no platform SDK dependency: everything here runs wherever `Display.getInstance().isGpuSupported()` is true, which includes the simulator, and adds nothing to the build for apps that don't use it.
+
+[IMPORTANT]
+====
+Like `com.codename1.gpu.Renderer`, the `VRRenderer` and `TextureSource` callbacks run on the platform render thread that owns the GPU context - never touch Codename One UI components from them. Everything else in the package is ordinary EDT-friendly component API.
+====
+
+=== Concepts
+
+[cols="1,3"]
+|===
+|Type |Role
+
+|`VRView`
+|The stereo component: clears the frame, splits the viewport per eye, positions the cameras from head tracking and invokes your renderer once per eye.
+
+|`VRRenderer`
+|Your scene callback: `onInit`, `onEyeFrame(device, eye, camera)` and `onDispose`.
+
+|`VREye`
+|Which eye a frame is for: `LEFT`, `RIGHT`, or `CENTER` in mono mode.
+
+|`VRSettings`
+|Interpupillary distance (default 0.064m), per-eye field of view, clip planes and the stereo default.
+
+|`HeadTracker`
+|Wires the gyroscope, accelerometer and magnetometer into an orientation with thread-safe snapshots for the render thread.
+
+|`OrientationFilter`
+|The deterministic sensor-fusion math behind the tracker, usable on its own.
+
+|`VRCameraRig`
+|Per-eye camera math over the existing `com.codename1.gpu.Camera`, usable without `VRView` for custom pipelines.
+
+|`Media360View`
+|A 360-degree panorama viewer: an equirectangular image on the inside of a sphere with drag or gyroscope look-around.
+
+|`TextureSource`
+|Extension point feeding dynamic textures (procedural animation, future video) to `Media360View`.
+|===
+
+=== Getting started: A stereo scene
+
+A `VRRenderer` draws the same scene for every eye; the camera differences produce the depth effect. The view configures the viewport and camera before each `onEyeFrame`, so the renderer only issues draw calls:
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/vr/VrSnippets.java[tag=stereoScene,indent=0]
+----
+
+`setStereo(false)` switches to a single centered viewpoint (`VREye.CENTER`) at runtime, useful for a non-headset preview of the same scene. `setPosition(x, y, z)` moves the viewer through the world; `setClearColor(argb)` sets the background.
+
+image::img/vr-stereo-scene.png[A stereo scene on an Android phone; the offset between the eye views is the depth cue,scaledwidth=30%]
+
+=== Head tracking
+
+`VRView` starts its `HeadTracker` when the component appears and stops it when it leaves the screen; the sensors draw power only between the two. The tracker fuses the gyroscope with the accelerometer (tilt reference) and, when present, the magnetometer (yaw reference) through a complementary filter - tune the blend via `getHeadTracker().getFilter().setGyroWeight(float)`.
+
+Call `recenter()` to make the current view direction the new "straight ahead," keeping pitch and roll - the standard VR recentering gesture. On devices without a gyroscope the tracker falls back to accelerometer tilt: pitch and roll stay accurate but yaw has no stable reference. `HeadTracker.isSupported()` reports whether any usable motion hardware exists; without it the orientation simply stays put and the scene still renders.
+
+=== The 360 photo viewer
+
+`Media360View` displays equirectangular panoramas - the format produced by 360 cameras and phone panorama modes, where longitude maps to X and latitude to Y:
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/vr/VrSnippets.java[tag=photoViewer,indent=0]
+----
+
+image::img/vr-360-panorama.png[An equirectangular panorama in side-by-side stereo,scaledwidth=40%]
+
+Dragging looks around with the grab-the-world gesture; `setHeadTrackingEnabled(true)` adds gyroscope look composed with the drag, and `setStereo(true)` renders side by side for cardboard-style viewers. Photo spheres are captured from a single point, so stereo intentionally uses zero eye separation - there is no parallax information in the image to reproduce. `setYaw`/`setPitch` position the view programmatically and `reset()` returns to straight ahead.
+
+=== 360 video and dynamic content
+
+There is no platform path from media frames to GPU textures yet, so 360 video isn't supported directly. `TextureSource` is the extension point for dynamic content: the view calls `createTexture` once on the render thread and `updateTexture` before every frame, so procedurally animated panoramas work today and a future media-to-texture bridge can plug in without API changes.
+
+[source,java]
+----
+include::../demos/common/src/main/java/com/codenameone/developerguide/vr/VrSnippets.java[tag=textureSource,indent=0]
+----
+
+=== The simulator
+
+Both `VRView` and `Media360View` run in the simulator through the desktop 3D backend, and the Simulate menu's *Motion / Gesture Simulation* window feeds synthetic sensor data to the `HeadTracker`, so head-tracked scenes are drivable from the desktop. Drag-look in `Media360View` works with the mouse as it does with a finger.
+
+=== Limitations and notes
+
+- *Lens distortion*: the stereo output is undistorted side-by-side rendering. Barrel distortion for lens-based viewers requires an offscreen render pass the portable GPU API doesn't expose yet, so there is no distortion setting to configure.
+- *Battery*: continuous rendering plus live sensors is the most power-hungry mode a phone UI can run; stop or pause the view whenever it isn't visible (the component does this automatically on hide).
+- *Coordinates*: the world frame matches the AR and 3D graphics APIs (meters, right-handed, Y up, -Z forward), letting content and math move between the three without conversion.
