Quick look

// Android — Jetpack Compose
SceneView(modifier = Modifier.fillMaxSize()) {
    rememberModelInstance(modelLoader, "models/helmet.glb")?.let {
        ModelNode(modelInstance = it, scaleToUnits = 1.0f, autoAnimate = true)
    }
}

// iOS — SwiftUI
SceneView(environment: .studio) {
    ModelNode(named: "helmet.usdz")
        .scaleToUnits(1.0)
}

<script> SceneView.modelViewer("canvas", "model.glb") </script>

# Claude — ask AI to build your 3D app
claude mcp add sceneview -- npx sceneview-mcp
# Then ask: "Build me an AR app with tap-to-place furniture"

No engine boilerplate. No lifecycle callbacks. The runtime handles everything.

The Compose-native successor to Sceneform

Google archived Sceneform in 2021 and ships no first-party declarative AR renderer — its current ARCore samples hand-roll a throwaway OpenGL framework instead. SceneView fills that gap. It descends from the maintained Sceneform community fork and is the actively-developed, Jetpack-Compose-native way to build 3D and AR on Android:

ARCore for perception (plane detection, anchors, depth, geospatial)
Filament for rendering (Google's production-grade real-time engine)
Jetpack Compose for the API — nodes are composables, lifecycle is automatic
glTF (.glb / .gltf) instead of the deprecated .sfb model format
Multiplatform — the same concepts run on iOS, Web, Desktop, TV, Flutter, and React Native

Coming from the archived Sceneform repo? See the migration guide for a concept-by-concept mapping (ArFragment → ARScene { }, ModelRenderable → rememberModelInstance, and so on).

3D scene

SceneView is a Composable that renders a Filament 3D viewport. Nodes are composables inside it.

val engine = rememberEngine()
val modelLoader = rememberModelLoader(engine)
val environmentLoader = rememberEnvironmentLoader(engine)

SceneView(
    modifier = Modifier.fillMaxSize(),
    engine = engine,
    modelLoader = modelLoader,
    environment = rememberEnvironment(environmentLoader) {
        environmentLoader.createHDREnvironment("envs/studio.hdr")
            ?: createEnvironment(environmentLoader)
    },
    cameraManipulator = rememberCameraManipulator()
) {
    // Model — async loaded, appears when ready
    rememberModelInstance(modelLoader, "models/helmet.glb")?.let {
        ModelNode(modelInstance = it, scaleToUnits = 1.0f, autoAnimate = true)
    }

    // Geometry — procedural shapes
    CubeNode(size = Size(0.2f))
    SphereNode(radius = 0.1f, position = Position(x = 0.5f))

    // Nesting — same as Column { Row { } }
    Node(position = Position(y = 1.0f)) {
        LightNode(apply = { type(LightManager.Type.POINT); intensity(50_000f) })
        CubeNode(size = Size(0.05f))
    }
}

Node types — 26+ composables

| Category | Nodes | What they do | |---|---|---| | Models | ModelNode | glTF/GLB with skeletal/morph animations. isEditable = true for gestures. | | Primitives | CubeNode · SphereNode · CylinderNode · ConeNode · TorusNode · CapsuleNode · PlaneNode | Procedural geometry, parametric size/segments | | Curves & shapes | LineNode · PathNode · ShapeNode | Single segments, polylines, extruded 2D polygons | | Custom geometry | GeometryNode · MeshNode | Direct Filament IndexBuffer / VertexBuffer | | Surfaces | ImageNode · VideoNode · BillboardNode | PNG/JPG plane, video plane (MediaPlayer), camera-facing sprite | | 3D text | TextNode | World-space text label that always faces the camera | | Compose-in-3D | ViewNode | Any Compose UI rendered as a 3D surface — buttons, lists, animations | | Lighting | LightNode · ReflectionProbeNode · DynamicSkyNode · FogNode | Sun/dir/point/spot lights, local IBL, time-of-day sky, atmospheric fog | | Physics | PhysicsNode | Simple rigid-body simulation (gravity, collisions) | | Cameras | CameraNode · SecondaryCamera | Main and picture-in-picture cameras | | Group | Node | Empty pivot for nesting and transform inheritance |

AR scene

ARSceneView is SceneView with ARCore. The camera follows real-world tracking.

var anchor by remember { mutableStateOf<Anchor?>(null) }

ARSceneView(
    modifier = Modifier.fillMaxSize(),
    planeRenderer = true,
    onSessionUpdated = { _, frame ->
        if (anchor == null) {
            anchor = frame.getUpdatedPlanes()
                .firstOrNull { it.type == Plane.Type.HORIZONTAL_UPWARD_FACING }
                ?.let { frame.createAnchorOrNull(it.centerPose) }
        }
    }
) {
    anchor?.let {
        AnchorNode(anchor = it) {
            ModelNode(modelInstance = helmet, scaleToUnits = 0.5f)
        }
    }
}

Plane detected → anchor set → Compose recomposes → model appears. Clear anchor → node removed. AR state is just Kotlin state.

AR node types

| Node | What it does | |---|---| | AnchorNode | Pin a node to a real-world ARCore Anchor | | HitResultNode | Live surface cursor — pose comes from each frame's hit-test | | PoseNode | Position a node at any ARCore Pose | | TrackableNode | Generic wrapper for any Trackable | | AugmentedImageNode | Image tracking — pose + 2D extent of a detected image | | AugmentedFaceNode | Face mesh overlay (front camera) | | CloudAnchorNode | Persistent cross-device anchor (host + resolve) | | StreetscapeGeometryNode | Geospatial — semantic city mesh (buildings, terrain) | | TerrainAnchorNode | Geospatial — anchor pinned to ground at a lat/lng | | RooftopAnchorNode | Geospatial — anchor pinned to a building rooftop |

AR features

Every ARCore feature surfaced as a Compose-friendly API:

| Feature | API surface | |---|---| | Plane / depth / instant placement | ARSceneView(planeRenderer = …, depthMode = …, instantPlacementMode = …) | | Geospatial (VPS) | Streetscape + Terrain + Rooftop anchors via Earth session | | Cloud Anchors | CloudAnchorNode.host(ttlDays = N) + .resolve(id) | | Augmented Faces & Images | AugmentedFaceNode, AugmentedImageDatabase, runtime image add | | Image Stabilization (EIS) | ARSceneView(imageStabilizationMode = ImageStabilizationMode.EIS) | | Camera exposure & focus | ARSceneView(cameraConfig = …), ARSceneScope.exposureCompensation | | Record & Replay | rememberARRecorder() to capture, ARSceneView(playbackDataset = file) to replay 1:1 — debug AR without a phone | | Rerun.io live debug | rememberRerunBridge() streams poses/planes/clouds to the Rerun viewer + a hosted /rerun/?url=… replay | | Permission flow | ARPermissionHandler — auto-detected from ComponentActivity |

See docs/docs/ar-recording.md, RECORDING_PLAYBACK.md, and the AR Debug — Rerun.io section in llms.txt.

Capabilities

What you can do across all 3D and AR scenes — beyond placing nodes.

| Capability | What it gives you | Where it lives | |---|---|---| | Gestures | Drag, pinch-to-scale, two-finger rotate, elevate, tap. Per-node opt-in via isEditable. | NodeGestureDelegate, OnGestureListener | | Animations | Skeletal/morph from glTF, plus per-node spring/property/smooth-transform. | ModelNode.playAnimation(), NodeAnimationDelegate | | Physics | Rigid-body dynamics — gravity, collisions, impulses. Pure-KMP simulation (no JNI). | PhysicsNode, sceneview-core | | Collision & raycasting | Ray vs Box / Sphere intersections, hit-testing, frustum culling. | CollisionSystem, Ray, Box, Sphere | | Procedural geometry | Generators for cube/sphere/cylinder/cone/torus/capsule, plus extrusion from 2D shapes (Earcut + Delaunator). | sceneview-core geometry + triangulation | | HDR environment | IBL lighting + skybox from .hdr / .ktx. Async load + reactive swap. | EnvironmentLoader, rememberEnvironment | | Custom materials | Filament .filamat materials with parameters, plus built-in unlit / lit / overlay variants. | MaterialLoader | | Post-processing | Bloom, depth of field, SSAO, vignette, color grading, tone mapping. | View.bloomOptions, dynamicResolutionOptions, … | | Compose UI in 3D | Render any @Composable as a textured plane in world space — buttons, lists, animations, all interactive. | ViewNode + ViewNode.WindowManager | | Multiple cameras | Picture-in-picture, mini-map, security-camera views. | SecondaryCamera | | Reactive scene graph | Compose-driven recomposition: change state → tree updates. No imperative parent.addChild(). | SceneScope / ARSceneScope DSL |

Apple (iOS / macOS / visionOS)

Native Swift Package built on RealityKit. 19 node types mirroring the Android API.

SceneView(environment: .studio) {
    ModelNode(named: "helmet.usdz").scaleToUnits(1.0)
    GeometryNode.cube(size: 0.1, color: .blue).position(x: 0.5)
    LightNode.directional(intensity: 1000)
}
.cameraControls(.orbit)

AR on iOS:

ARSceneView(planeDetection: .horizontal) { position, arView in
    GeometryNode.cube(size: 0.1, color: .blue)
        .position(position)
}

Nodes available — ModelNode · GeometryNode (cube/sphere/cylinder/cone/torus/capsule/plane) · LightNode · ImageNode · VideoNode · TextNode · ViewNode · BillboardNode · MeshNode · LineNode · PathNode · ShapeNode · PhysicsNode · ReflectionProbeNode · DynamicSkyNode · FogNode · CameraNode · AugmentedImageNode · SceneReconstructionNode (visionOS scene mesh).

Plus the iOS RerunBridge with the same wire format as Android, and a NodeBuilder DSL for declarative composition outside SwiftUI.

Install: https://github.com/sceneview/sceneview.git (SPM, from 4.18.0)

SceneView Web (JavaScript + Kotlin/JS)

The lightest way to add 3D to any website. Two <script> tags, one function call. Friendly DSL (~25 KB) powered by Filament.js WASM (~210 KB) — the same engine behind Android SceneView.

<!-- 1. Filament.js engine (WASM) -->
<script src="https://cdn.jsdelivr.net/gh/sceneview/sceneview@v4.18.0/website-static/js/filament/filament.js"></script>
<!-- 2. SceneView wrapper -->
<script src="https://cdn.jsdelivr.net/gh/sceneview/sceneview@v4.18.0/website-static/js/sceneview.js"></script>
<script> SceneView.modelViewer("canvas", "model.glb") </script>

Note: the sceneview-web npm package is the lower-level Kotlin/JS UMD bundle — it expects a Filament global and does not include the friendly SceneView.modelViewer DSL. Use the snippet above for vanilla-JS sites. The npm package is intended for Kotlin/JS or webpack-based projects.

JavaScript API (script-tag):

SceneView.modelViewer(canvasOrId, url, options?) — all-in-one viewer with orbit + auto-rotate
SceneView.create(canvasOrId, options?) — empty viewer, load model later
viewer.loadModel(url) — load/replace glTF/GLB model
viewer.setAutoRotate(enabled) — toggle rotation
viewer.dispose() — clean up resources

WebXR — AR & VR in the browser

const ar = await SceneView.startAR("canvas", { hitTest: true })   // immersive-ar
const vr = await SceneView.startVR("canvas")                       // immersive-vr

| Class | Mode | Use | |---|---|---| | ARSceneView | immersive-ar | Phone passthrough AR with hit-test, anchors, light estimation | | VRSceneView | immersive-vr | Headset VR with controller input, reference spaces | | WebXRSession | both | Low-level frame loop, XRHitTestSource, XRReferenceSpace |

Kotlin/JS power-user API

For Kotlin Multiplatform projects, the same engine is exposed as a Kotlin/JS class with an OrbitCameraController, a geometry DSL, and reactive node updates:

implementation("io.github.sceneview:sceneview-web:4.18.0")

Install: npm install sceneview-web or CDN — Landing page — Playground — npm

Use with AI

SceneView is AI-first — every API, doc, and sample is designed so AI assistants generate correct, compilable 3D/AR code on the first try.

MCP Server (Claude, Cursor, Windsurf, etc.)

The official MCP server provides 28 tools, 33 compilable samples, a full API reference, and a code validator:

# Claude Code — one command
claude mcp add sceneview -- npx sceneview-mcp

# Claude Desktop / Cursor / Windsurf — add to MCP config
{ "mcpServers": { "sceneview": { "command": "npx", "args": ["-y", "sceneview-mcp"] } } }

Highlights: generate_scene, debug_issue, search_models (Sketchfab BYOK), analyze_project (audit existing app), validate_code (compile-check before sending), plus per-platform recipes for AR, physics, geometry, and Compose-in-3D.

Claude Code plugin (MCP + slash commands + hooks)

Want the MCP server plus the full SceneView contributor toolkit (one-shot release, review, cross-platform sync, version-bump, etc.) in a single install? Use the SceneView Claude Code marketplace:

/plugin marketplace add sceneview/claude-marketplace
/plugin install sceneview@sceneview

You get:

sceneview-mcp server — same as above, started automatically
namespaced slash commands — /sceneview:contribute, /sceneview:release, /sceneview:review (incl. --score / --coverage / high — absorbs the former /evaluate + /test), /sceneview:document, /sceneview:quality-gate, /sceneview:sync-check, /sceneview:store-status, /sceneview:version-bump, /sceneview:maintain
Cross-platform reminder hooks — gentle nudges when you edit Android, iOS, Web, or KMP-core APIs to keep the other platforms in sync

Developer tools

AR Debug — hosted Rerun viewer

Tap Save & Share in the AR Rerun demo to flush a .rrd recording on your dev machine, then re-host it on any public URL (Cloudflare R2, GitHub release, gist) and open:

<https://sceneview.github.io/rerun/?url=<encoded-public-url>>

…in any browser to scrub the AR session frame-by-frame. No install, no Rerun viewer needed locally — perfect for attaching a fully-replayable session to a bug report. Powered by @rerun-io/web-viewer under SceneView branding.

See the AR Debug — Rerun.io section in llms.txt for the full architecture (live mode + save mode + control protocol) and the Kotlin API surface (RerunBridge.requestSaveAndShare).

Record & Replay AR sessions

Record & Replay AR sessions — capture an outdoor ARCore session once with ARRecorder, replay it 1:1 at the desk via ARSceneView(playbackDataset = file). Pair with the Rerun bridge for record-replay-inspect debugging. See docs/docs/ar-recording.md and the Record & Playback demo.
