Usage

val engine = rememberEngine()
val modelLoader = rememberModelLoader(engine)
val environmentLoader = rememberEnvironmentLoader(engine)
Scene(
    modifier = Modifier.fillMaxSize(),
    engine = engine,
    modelLoader = modelLoader,
    childNodes = rememberNodes {
        add(ModelNode(modelLoader.createModelInstance("model.glb")).apply {
            // Move the node 4 units in Camera front direction
            position = Position(z = -4.0f)
        })
    },
    environment = environmentLoader.createHDREnvironment("environment.hdr")!!
)

Sample

AR Model Viewer

val engine = rememberEngine()
val modelLoader = rememberModelLoader(engine)
val model = modelLoader.createModel("model.glb")
var frame by remember { mutableStateOf<Frame?>(null) }
val childNodes = rememberNodes()
ARScene(
    modifier = Modifier.fillMaxSize(),
    engine = engine,
    modelLoader = modelLoader,
    onSessionUpdated = { session, updatedFrame ->
        frame = updatedFrame
    },
    onGestureListener = rememberOnGestureListener(
        onSingleTapConfirmed = { motionEvent, node ->
            val hitResults = frame?.hitTest(motionEvent.x, motionEvent.y)
            val anchor = hitResults?.firstOrNull {
                it.isValid(depthPoint = false, point = false)
            }?.createAnchorOrNull()

            if (anchor != null) {
                val anchorNode = AnchorNode(engine = engine, anchor = anchor)
                anchorNode.addChildNode(
                    ModelNode(modelInstance = modelLoader.createInstance(model)!!)
                )
                childNodes += anchorNode
            }
        }
    )
)
