Allow mutable settings to scene camera with OrbitControls

[fluwer]

How can I limit the camera's capabilities? For example, use:

controls.enableZoom = false;
controls.enableRotate = false;
controls.enablePan = false;

Hi @fluwer,

Currently there's no easy way to configure the camera controls. Especially because the scene.controls object is re-created during initialization, we can't simply disable features "on init".

But here is a workaround. We can re-define the controls property and disable features when new controls are set:

scene.on('init', js_handler=f'''() => {{
    const scene = getElement({scene.id});
    let _controls = scene.controls;
    Object.defineProperty(scene, 'controls', {{
        configurable: true,
        enumerable: true,
        get() {{ return _controls; }},
        set(newControls) {{
            _controls = newControls;
            newControls.enableZoom = false;
            newControls.enableRotate = false;
            newControls.enablePan = false;
        }},
    }});
}}''')

Got it, sad news that this object is being recreated at runtime. However, you provided a solution, and it works perfectly, that's great!
In that case, this idea will probably go into the archives.

Thanks again!

Let's keep the feature request open. We can see if it gets upvoted and if someone wants to give it a shot to make the configuration more accessible.
