Rotate camera slowly to a target

Questions
1

I come from Unity background and if we want to move/rotate an object slowly to a certain position/rotation, we use Time.deltaTime in Update function. Is there a similar approach in Babylon? Such that by press of a key (Key.A), the camera moves/rotates slowly to a given position/rotation? The Vector3 will be set by me through code.

            var scene = new BABYLON.Scene(engine);
            // This creates and positions a free camera (non-mesh)
            var camera = new BABYLON.ArcRotateCamera("Camera", Math.PI / 2, Math.PI / 2, 300, BABYLON.Vector3.Zero(), scene);
            // This targets the camera to scene origin
            camera.setTarget(BABYLON.Vector3.Zero());
            // This attaches the camera to the canvas
            camera.attachControl(canvas, true);

Hello,
You can use an animation to update the position of the camera target.
Take a look at the doc for more information:
https://doc.babylonjs.com/babylon101/animations

You can find an example of a very basic camera’s target animation in my neon demo, at line 274 of the PG, I use CreateAndStartAnimation on the ‘target’ property of the camera:

Another way to do the same is to update the rotation/position in the render loop but I think using animation is the easiest way to do it.

If you want to do it without animations. The equivalent of Time.deltaTime in Babylon is engine.getDeltaTime(). You can update the camera in one of the events (e.g. scene.onBeforeRenderObservable).

Sorry for the late reply. Can you please give an example of engine.getDeltaTIme()?
Such that the camera rotates to a target rotation (10,10,10).

Does a search in the playground help? If not, what specifically are you looking for?
