Hey leenalfalah. You can animate the camera's position just like any other object. For example:

See the Pen oNYmKQa?editors=0010 by GreenSock (@GreenSock) on CodePen

 

If you want to do something on scroll, you probably want to attach a ScrollTrigger. Probably something like this:

Hey @leenalfalah

 

Google led me to this:

 

https://discourse.threejs.org/t/animate-camera-zoom-and-controls-target/16583

 

And it indeed does seem to work

 

See the Pen e595e13b0cfcd9f289ae2ae5c016745d by akapowl (@akapowl) on CodePen

 

 

I'm not sure, wether the onUpdate is best to be placed inside the scrollTrigger-object or outside of it, though (or if it would make a difference).
