Hello! 
A good step will be writing code for handling pointer interaction: Interacting With Scenes | Babylon.js Documentation (babylonjs.com). In this case, you’ll want to handle the POINTERMOVE.
I believe creating a camera animation for this and easing the camera with bezier curves will also help achieving the smooth and tiny/mini effect.
