Using Manipulator [Android]

[paulosensorydata]

Hi everyone. I am trying to enable users to rotate a geometry around (Orbit-like) and I am setting a Manipulator but it doesn't seem to be working properly.

I have also a camera.lookAt on onResized() - does it overrides the manipulator? Tried to comment out this line, but still no success. What can be wrong?

        super.onCreate(savedInstanceState)

        surfaceView = SurfaceView(this)
        setContentView(surfaceView)

        choreographer = Choreographer.getInstance()
        displayHelper = DisplayHelper(this)
        setupSurfaceView()
        setupFilament()

        setupView()
        setupScene()
        initFilament()
    }

    private fun initFilament() {

        val manipulator = Manipulator.Builder()
            .targetPosition(200f, 200f, 0f)
            .orbitHomePosition(-400f, -400f, 800f)
            .viewport(surfaceView.width, surfaceView.height)
            .build(Manipulator.Mode.ORBIT)

        modelViewer = ModelViewer(surfaceView, engine, manipulator)

    }

    private fun setupFilament() {
        engine = Engine.create()
        renderer = engine.createRenderer()
        scene = engine.createScene()
        view = engine.createView()
        camera = engine.createCamera(engine.entityManager.create())
    }```

You shouldn't need to create your own Camera, ModelViewer should create one for you. This is the camera the Manipulator will be tied to.
