Also would be interested, espetialy for the smooth animation of camera movement.

no clue of this. But you can do smooth animations using mathematical physics, simply mocking forces. See [https://natureofcode.com](https://natureofcode.com) and [examples | p5.js](https://p5js.org/examples/simulate-forces.html)  
Also you can simply put a dampening scalar on the moving value. pos.x -= dampen  
OR you can feed the moving value into a easing curve as the val pos.x = ease(pos.x, target.x, speed)  
It works for any!!!  
then clamp when below a low value 0.0001 for example

Also slerp for rotations
