SceneView

3D & AR for every platform.

Build 3D and AR experiences with the UI frameworks you already know. Same concepts, same simplicity — Android, iOS, Web, Desktop, TV, Flutter, React Native.

Try the demo apps

See SceneView capabilities in action — install the live demos in one tap:

Browse all sample sources in samples/ — Android · iOS · Web · Desktop · TV · Flutter · React Native.

Tip — every demo opens directly via https://sceneview.github.io/open?demo=<id>. For example, …/open?demo=ar-rerun lands straight on the AR Rerun debug screen with a single tap from any QR code or link.

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.

3D scene

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

SceneView(
    modifier = Modifier.fillMaxSize(),
    engine = rememberEngine(),
    modelLoader = rememberModelLoader(engine),
    environment = rememberEnvironment(engine, "envs/studio.hdr"),
    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

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

AR features

Every ARCore feature surfaced as a Compose-friendly API:

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.

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 4.1.0)

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@v4.0.9/website-static/js/filament/filament.js"></script>
<!-- 2. SceneView wrapper -->
<script src="https://cdn.jsdelivr.net/gh/sceneview/sceneview@v4.0.9/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

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:4.0.0")

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

• 11 namespaced slash commands — /sceneview:contribute, /sceneview:release, /sceneview:review, /sceneview:test, /sceneview:document, /sceneview:quality-gate, /sceneview:publish-check, /sceneview:sync-check, /sceneview:version-bump, /sceneview:evaluate, /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.
