hey guys i am new to threejs and i am currently trying to adjust my camera angle such that it pulls itself backwards on scroll up to a certain level. i am trying to make it such that the 3d object becomes smaller on scroll by adjusting the camera angle. is there anyway to do that? thanks in advance
