Change Object parent in Three.js?

问题

Is it possible to change the parent of any object?

For example:

scene.add(Object);
Object.Add(OtherObject);
OtherObject.parent = scene; // <-- Something like this

I just know that I can remove the Object and create it again in the new parent, but I'll hope there's another way. I got some Object that are on a plane, if I click them I want fix them to the camera so I can see all the time in front of the camera. And If I click them Again I wanna set the parent again to the plane.

Why did this dont work?

var obj = clicked.clone();
camera.add(obj);
obj.position.set(0,0,-20);

Easiest way is to use the detach and attach functions of the THREE.SceneUtils object:

THREE.SceneUtils.detach( child, parent, scene );
THREE.SceneUtils.attach( child, scene, parent );
