SceneView for Web is the browser half of the SceneView SDK. It renders with Filament.js — the same Filament engine as SceneView Android, compiled to WebAssembly + WebGL2. It ships two API surfaces:
SceneView.create(canvas, configure = { … }) with atype-safe builder, plus ARSceneView / VRSceneView / WebXRSession for WebXR. This is the source-of-truth API; the package is built from sceneview-web/src/jsMain/.
<script> tag the libraryregisters itself on window.sceneview, exposing createViewer, modelViewer, etc. for use with no bundler and no Kotlin.
sceneview-web (currently 4.18.0).Firefox 78+, Safari 15+.
Always treat `llms.txt` in the repo root as the source of truth — its "SceneView Web (Kotlin/JS + Filament.js)" section carries the complete DSL, the JS API, the WebXR ARSceneView / VRSceneView / WebXRSession surface, and the threading rules. <https://github.com/sceneview/sceneview/blob/main/llms.txt>
The Kotlin/JS source lives in sceneview-web/src/jsMain/kotlin/io/github/sceneview/web/ — SceneView.kt (the DSL + SceneViewBuilder), SceneViewJS.kt (the JS-facing SceneViewer class), Main.kt (the window.sceneview bindings), and xr/ (WebXR). The samples/web-demo/ app is a working reference.
Trigger on any of:
<script> tag."Skip for raw Three.js, Babylon.js, <model-viewer>, A-Frame, or PlayCanvas work that does NOT use sceneview-web.
filament.js MUST load before sceneview-web.js:
<canvas id="viewer" style="width:100%;height:100vh;display:block"></canvas>
<script src="https://sceneview.github.io/js/filament/filament.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/sceneview-web.js"></script>
<script>
sceneview.modelViewer('viewer', 'https://sceneview.github.io/models/platforms/DamagedHelmet.glb')
.then(function (sv) { sv.setAutoRotate(true); });
</script>npm install sceneview-web filamentThe JS API is registered on window.sceneview after the script loads. Verified against Main.kt (jsModelViewer, jsCreateViewer):
// Simplest — creates a viewer and loads a model
sceneview.modelViewer('viewer', 'model.glb')
.then(function (sv) {
sv.setAutoRotate(true);
sv.setBackgroundColor(0.05, 0.05, 0.12, 1.0); // RGBA 0-1
sv.setEnvironment('studio_ibl.ktx');
});
// More control
sceneview.createViewer('viewer').then(function (sv) {
sv.loadModel('model.glb').then(function () { sv.fitToModels(); });
}).catch(function (err) {
// The Promise REJECTS if Filament fails to initialize — handle it,
// don't assume createViewer always resolves.
console.error('SceneView init failed', err);
});SceneViewer instance methods (from SceneViewJS.kt): loadModel(url) → Promise, setEnvironment, setEnvironmentWithSkybox, setCameraOrbit, setCameraTarget, setAutoRotate, setAutoRotateSpeed, setZoomLimits, setBackgroundColor, fitToModels, startRendering, stopRendering, resize, dispose.
Verified against SceneView.kt (create, SceneViewBuilder):
SceneView.create(
canvas = canvas, // HTMLCanvasElement
configure = {
camera {
eye(0.0, 1.5, 5.0)
target(0.0, 0.0, 0.0)
fov(45.0)
}
light {
directional()
intensity(100_000.0)
direction(0.6f, -1.0f, -0.8f)
}
model("models/helmet.glb") { autoAnimate(true) }
cameraControls(true)
autoRotate(true)
},
onError = { error -> console.error(error) }, // init failed — wire to your reject path
onReady = { sceneView -> sceneView.startRendering() }
)Verified against xr/ARSceneView.kt. AR session creation MUST happen inside a user-gesture handler (a click/tap listener):
ARSceneView.checkSupport { supported ->
if (supported) {
// call ARSceneView.create from a click handler
ARSceneView.create(
canvas = canvas,
features = WebXRSession.Features(
required = arrayOf(XRFeature.HIT_TEST),
optional = arrayOf(XRFeature.DOM_OVERLAY, XRFeature.LIGHT_ESTIMATION)
),
onError = { msg -> console.error(msg) },
onReady = { arView ->
arView.onHitTest = { pose -> arView.loadModel("models/chair.glb") }
arView.onSelect = { source -> /* user tapped */ }
arView.start()
}
)
}
}WebXR VR uses the same shape via VRSceneView; WebXRSession is the lower-level unified AR+VR API. See llms.txt § WebXR.
Filament module present at init. Use <script> tags, not ES imports, for the no-bundler path.
createViewerImplfalls back to clientWidth/clientHeight if width/height are 0, so the canvas must be laid out (e.g. 100vw/100vh or fixed px) before createViewer runs.
SceneView.create and loadModel arePromise-based — .then(...)/await them before calling instance methods. loadModel's onLoaded fires only once external textures are fetched.
requestSession outside a click/tap handler. Always checkSupport first, then call ARSceneView.create / VRSceneView.create from the handler.
Filament calls run on the main thread. Never call destroy()/dispose() inside an animation-frame callback; defer to the next microtask.
Safari iOS 18+. VR: Meta Quest Browser, desktop Chrome with a headset. Always gate on checkSupport and provide a non-XR fallback.
sceneview-web exposes a SceneViewHaptic class that wraps the browser Vibration API (navigator.vibrate(...)) behind the same seven semantic presets as the Android and iOS libraries, so cross-platform code paths stay symmetric.
// Plain JS — `sceneview.haptic` is a ready-to-use singleton:
sceneview.haptic.light(); // tap
sceneview.haptic.success(); // confirmation
sceneview.haptic.continuous(1.0, 200); // 200 ms; intensity ignored on Web
sceneview.haptic.pattern([10, 50, 20]);// custom on/off durations (ms)light() medium() heavy() success() warning()error() selection(). Plus continuous(intensity, durationMs) and pattern(durationsMs[]).
knob — so the intensity argument is accepted for cross-platform parity but ignored at runtime.
navigator.vibrate;every call is then a silent no-op. Some browsers also restrict vibration to user-gesture handlers. See llms.txt § Haptic Feedback.
Preallocate scratch arrays and mutate them in place — never build fresh `[x, y, z]` / `float3(...)` / mat4 array literals inside a `requestAnimationFrame` tick. Filament.js reads the array synchronously, so reuse is safe, and the small JS heap on iOS Safari turns per-frame allocation into a GC sawtooth that drops frames. SceneView's own OrbitCameraController keeps eyeScratch / centerScratch / upScratch and rewrites them per frame instead of allocating — follow that pattern in your render loop.
