SceneView

The AI-first 3D & AR SDK for Jetpack Compose, SwiftUI 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, RealityKit + ARKit on Apple, Filament.js + WebXR in the browser — with Flutter, React Native and Compose Multiplatform bridges on top. Open source, Apache 2.0.

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.

Try it

   

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 Rerun AR Replay, a real AR session rebuilt in 3D.

Quick start

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

Android

// build.gradle.kts
implementation("io.github.sceneview:sceneview:4.56.0")

@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.

AR (Android)

// build.gradle.kts
implementation("io.github.sceneview:arsceneview:4.56.0")   // includes the 3D module

@Composable
fun ARScreen() {
    var anchor by remember { mutableStateOf(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) }
            }
        }
    ) {
        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).
