Take a look at this alteration of that playground
After creating the sphere I call
camera.setTarget(sphere).. In the original the target is set to
ArcRotateCamera.setTarget is called with the vector (like above) the camera can pan away from that point with the right mouse button.
The functionality for moving the camera is added in the line below lil FYI
does setting the camera target the sphere produce the effect you’re looking for?.
