The AI-first 3D & AR SDK for Jetpack Compose — and the web.

Declarative 3D and AR for app developers who want a model on screen, or in the room, without a game engine: Filament + ARCore on Android, Filament.js + WebXR in the browser, and a Compose Multiplatform viewer. It is the maintained successor to Google Sceneform. Open source, Apache 2.0.

Moving from Sceneform, or from SceneView 2.x code (Scene(childNodes = …), ARScene)? The mapping. Which artifact fits your app: 3D and AR library, per platform.

Used in production. More than 1,300 stars on GitHub, and over 500 public repositories declare SceneView as a dependency. It ships in Medal, IKEA, Lenskart and Safie on Google Play, is declared by the open-source apps Bitkey (Block) and Vocable (WillowTree), and is a dependency of the GeneXus Augmented Reality module and the TruVideo camera SDK. The Niantic Spatial SDK samples use it for AR.

AI-first means one thing here: an assistant that reads llms.txt or the MCP server writes SceneView code that works on the first try. When it doesn't, the API or the doc gets fixed.

The demo apps are built from samples/. Any demo opens straight from a link: https://sceneview.github.io/open?demo=<id>. Start with Cosmos, the galaxy the catalogue opens on, or 3D Scan, a space scanned with ARCore and rebuilt in 3D.

_{A living room scanned in 3D Scan on a Pixel 9, then rebuilt as a model (sped up).}

Install the Android demo, record your screen while you use a demo, and tell us what breaks or confuses you: open an issue with the recording attached, or send it from the app (any demo, Settings, then Send feedback).

One minimal, working example per platform. The full reference for each is in llms.txt.

// build.gradle.kts
implementation("io.github.sceneview:sceneview:4.68.0")

The app module needs compileSdk = 37, minSdk 24 or higher, AGP 9.4.0+, Kotlin 2.3 or newer and JVM target 21 for both Java and Kotlin: SceneView ships Java 21 bytecode with public inline functions. The quickstart requirements give the Gradle snippet and the reason for each.

Stuck on AGP 8 / compileSdk 36 / Kotlin 2.2? Use 4.18.0, the newest release that builds there.

import androidx.compose.foundation.layout.fillMaxSize
import androidx.compose.runtime.Composable
import androidx.compose.ui.Modifier
import io.github.sceneview.SceneView
import io.github.sceneview.rememberModelInstance

@Composable
fun ModelScreen() {
    SceneView(modifier = Modifier.fillMaxSize()) {          // orbit camera + default lighting
        rememberModelInstance(modelLoader, "models/helmet.glb")?.let { instance ->
            ModelNode(modelInstance = instance, scaleToUnits = 1.0f, autoAnimate = true)
        }
    }
}

models/helmet.glb lives in src/main/assets/. rememberModelInstance returns null until the model is loaded, then recomposes. Never call modelLoader.createModel* from a background coroutine: Filament calls must run on the main thread, and rememberModelInstance handles that.

// build.gradle.kts
implementation("io.github.sceneview:arsceneview:4.68.0")   // includes the 3D module

import androidx.compose.foundation.layout.fillMaxSize

import io.github.sceneview.ar.arcore.getUpdatedPlanes
import io.github.sceneview.rememberModelInstance

@Composable
fun ARScreen() {
    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 { it.createAnchorOrNull(it.centerPose) }
            }
        }
    ) {
        val helmet = rememberModelInstance(modelLoader, "models/helmet.glb")
        anchor?.let { a ->
            AnchorNode(anchor = a) {
                helmet?.let { ModelNode(modelInstance = it, scaleToUnits = 0.5f) }
            }
        }
    }
}

Plane detected → anchor set → Compose recomposes → the model appears. AR state is just Kotlin state. For placement without a tap, grounded and gesture-ready, start from AutoPlacementScene (see llms.txt).

arsceneview already declares the CAMERA permission and marks ARCore as optional. An AR Optional app declares android.hardware.camera.ar and android.hardware.camera as <uses-feature … android:required="false" />; an AR Required app overrides the ARCore value with tools:replace="android:value". Both snippets are in the AR manifest section.

A viewer by design — load, orbit, light, tap; no AR. Scope and the one-time iOS setup: sceneview-compose/.

SceneView for SwiftUI (SceneViewSwift), Flutter (flutter_sceneview) and React Native (@sceneview-sdk/react-native) is deprecated: 4.68.0 is their last release. Published versions stay installable and the source stays in this repository — what that means and the timeline.

codex  mcp add sceneview -- npx -y sceneview-mcp   # Codex

Then ask: "Add a 3D model viewer to my Compose screen." Every other client is in Use with AI.

Each row is a published package plus an app or page you can open today, backed by a real capture of it.

Platform	Status	Install	Open it	Capture
Android	Shipped · Stable	Maven Central	Google Play
iOS	Shipped · Alpha	Swift Package	App Store
Web	Shipped · Alpha	npm sceneview-web	Live web demo

Shipped means released and publicly reachable; the second word is the API maturity. The other platforms in the table below join this section once a capture backs them.

Everything an assistant needs to write SceneView code ships with the SDK:

• llms.txt — the complete API reference in one file: composables, every node type, threading rules, recipes. Its Kotlin snippets are compiled in CI. Served at https://sceneview.github.io/llms.txt for tools without MCP support.
• Rules files — AGENTS.md (Codex, Cursor, GitHub Copilot, Gemini in Android Studio and others), CLAUDE.md (Claude Code), .github/copilot-instructions.md, and .cursorrules for older Cursor versions.
• The MCP server — free, no API key. The tools assistants reach for most: validate_code (checks a snippet for known pitfalls and unknown symbols before you run it; it does not check argument names), get_node_reference (the exact node signature, not an invented one), list_samples / get_sample (38 samples to start from), and get_setup / get_ar_setup (project wiring).

Clients that only speak HTTP (Gemini in Android Studio, ChatGPT) use the hosted endpoint https://mcp.sceneview.dev/mcp, or run their own with npx sceneview-mcp --http. Per-client snippets: sceneview.github.io/#ai-setup. Listed on the MCP Registry.

This repository is also an OpenAI plugin: .codex-plugin/plugin.json points at the three skills under agents/ (sceneview, sceneview-ios, sceneview-web). From a checkout:

codex plugin marketplace add "$PWD"    # absolute path — a relative one does not resolve
codex plugin add sceneview@sceneview-local

Codex also discovers the skills from .agents/skills/ on its own. Over HTTP the MCP server carries an inline view_3d_model widget that renders a public GLB/glTF URL in the conversation. Listing copy and test prompts: agents/OPENAI-PLUGIN.md.

/plugin marketplace add sceneview/claude-marketplace, then /plugin install sceneview@sceneview, installs the same three skills as the Codex plugin together with the MCP server. The commands used to work on this repository are a separate plugin, sceneview-contrib@sceneview — see sceneview/claude-marketplace.

Vertical MCP servers (Rerun AR debugging and others) are listed in the MCP README.

SceneView is a composable that renders a Filament 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(type = LightManager.Type.POINT, apply = { intensity(50_000f) })
        CubeNode(size = Size(0.05f))
    }
}

ARSceneView is SceneView with ARCore: the camera follows real-world tracking. See the AR quick start above.

There is no per-format API on Android: rememberModelInstance(modelLoader, path) accepts all of them. On Apple, RealityKit reads no glTF, so .gltf / .glb are deliberately not in ModelFormat; USD/Reality load through RealityKit and the mesh formats through MeshAsset. The format is decided by the file's bytes, not its extension, so a file shared into your app as application/octet-stream with no name still opens. The converters are dependency-free Kotlin in sceneview-core. Tracked next: one ModelFormat entry point and every format on the web. Details: Model formats.

Native Swift Package built on RealityKit, with a node set mirroring the Android API. Content you can build synchronously uses the @NodeBuilder form:

SceneView {
    GeometryNode.cube(size: 0.1, color: .blue)
        .position(.init(x: 0.5, y: 0, z: 0))
    LightNode.directional(intensity: 1000)
}
.environment(.studio)
.cameraControls(.orbit)

AR on iOS — tap a detected plane to place content:

ARSceneView(
    planeDetection: .horizontal,
    onTapOnPlane: { position, arView in
        let anchor = AnchorNode.world(position: position)
        anchor.add(GeometryNode.cube(size: 0.1, color: .blue).entity)
        arView.scene.addAnchor(anchor.entity)
    }
)

Nodes — ModelNode · GeometryNode (cube/sphere/cylinder/cone/torus/capsule/plane) · LightNode · ImageNode · VideoNode · TextNode · ViewNode · BillboardNode · MeshNode · LineNode · PathNode · ShapeNode · PhysicsNode · ReflectionProbeNode · DynamicSkyNode · FogNode · CameraNode · AnchorNode · AugmentedImageNode · SceneReconstructionNode (visionOS scene mesh). Plus an iOS RerunBridge with the same wire format as Android.

Full guide: SceneViewSwift/README.md.

Two <script> tags and one call (see Web above). The wrapper is ~24 KB gzipped; the engine it drives is Filament — the same renderer as Android SceneView — compiled to WebAssembly (~2.3 MB gzipped).

JavaScript API (script tag):

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

Kotlin/JS (sceneview-web, npm only) — the power-user API: OrbitCameraController, the geometry DSL, reactive node updates, and WebXR through ARSceneView (immersive-ar, hit-test, anchors, light estimation), VRSceneView (immersive-vr, controllers) and the low-level WebXRSession. The module builds a webpack bundle, so it has no Maven coordinate:

npm install sceneview-web

The package expects a Filament global and does not include the SceneView.modelViewer script helpers. A Kotlin Multiplatform project that only needs the shared core (collision, math, geometry, animation, physics — no renderer) uses implementation("io.github.sceneview:sceneview-core-js:4.68.0").

Google archived Sceneform in 2021 and ships no first-party declarative AR renderer. SceneView descends from the maintained Sceneform community fork: ARCore for perception, Filament for rendering, Jetpack Compose for the API, and glTF (.glb / .gltf) instead of the deprecated .sfb format.

Coming from Sceneform? The migration guide maps it concept by concept (ArFragment → ARSceneView { }, ModelRenderable → rememberModelInstance, and so on).

• Record & Replay — capture an ARCore session once with rememberARRecorder(), replay it 1:1 at your desk with ARSceneView(playbackDataset = file). See docs/docs/ar-recording.md and the Record & Playback demo.
• Hosted Rerun viewer — export a scan's Rerun recording from the 3D Scan demo, host the .rrd file at an https address that ends in .rrd, and open https://sceneview.github.io/rerun/?url=<encoded-url> to scrub the session frame by frame in a browser, with no local install. The host has to allow cross-origin requests (CORS): a public GitHub repository's raw.githubusercontent.com link and GitHub Pages do, a GitHub release asset does not (checked 2026-10-13); an R2 or S3 bucket does with a CORS rule that allows https://sceneview.github.io. Architecture and the Kotlin API (RerunBridge.requestSaveAndShare) are in the AR Debug — Rerun.io section of llms.txt.

Each platform uses its native renderer. Shared logic lives in Kotlin Multiplatform.
