Point ArcRotateCamera at position?

Questions

I’d like to, when I click, center the camera on the clicked sphere in this playground.
Not target the sphere, but position the camera such that the sphere is between the camera and the target.

camera.target = {positionVector}
or
camera.setTarget({positionVector})
probably

or maybe .position somewhere along the line from the center through the sphere

The target of the camera is the point it rotates around. I want to still be rotating about the center of the scene while looking at the clicked mesh. As though I manually left-click-dragged the screen to place the mesh in the center.

As for position, you can’t set the position of an ArcRotateCamera. If I could find the alpha and beta of a mesh relative to a target I could set that instead, but I’m not sure that’s possible.

No?
Somewhere along the circle or sphere?

Might have to get creative or end up in quaternion territory.

Oh you’re right, my bad. I was trying to set the position itself; didn’t realize setPosition was a thing.

Thanks~
