How can I set a new center of the map?

[myfoxtail]

I've tried to do a lot of these...

controls.controls.target.x = point.x;
controls.controls.target.z = point.y;
controls.controls.update();

controls.moveTo(new VIZI.Point(point.x, point.y, point.z)); (seems to be the same as 1)
map.updateView(new VIZI.LatLon(point.x, point.y), point.z);
map.camera.lookAt(new VIZI.Point(point.x, point.y, point.z));

..but nothing works well.
Can you help me with this issue?
May it be the problem in that tiles render only in viewport and if the new center is much further it can't be located?
