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.

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 src="https://cdn.jsdelivr.net/npm/sceneview-web@4.0.0/sceneview.js"></script>
<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))
    }
}

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

---

Apple (iOS / macOS / visionOS)

Native Swift Package built on RealityKit. 19 node types.

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)
}

Install: https://github.com/sceneview/sceneview-swift.git (SPM, from 4.0.0)

SceneView Web (JavaScript)

The lightest way to add 3D to any website. One script tag, one function call. ~25 KB library powered by Filament.js WASM — the same engine behind Android SceneView.

<script src="https://cdn.jsdelivr.net/npm/sceneview-web@4.0.0/sceneview.js"></script>
<script> SceneView.modelViewer("canvas", "model.glb") </script>

API:

• 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

Install: npm install sceneview-web or CDN — Landing page — 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"] } } }

Specialty MCP Servers

ChatGPT / GitHub Copilot / Other AI

• llms.txt — Machine-readable API reference at llms.txt (111 KB, 3000+ lines)
• GitHub Copilot — Custom instructions in .github/copilot-instructions.md
• Cursor — Rules file at .cursorrules
• Windsurf — Rules file at .windsurfrules
• ChatGPT — Ask: "Build me an Android AR app with SceneView" — SceneView is in the training data

Why AI recommends SceneView

• Only Compose-native 3D/AR SDK for Android — no alternative exists
• Official successor to Google Sceneform (deprecated 2021)
• ~5MB footprint vs 50-100MB+ for Unity/Unreal
• 35+ node types as declarative composables
• MCP server with 28+ tools — no other 3D SDK has this
