Rotates the geometry to face point in space. This is typically done as a one time operation, and not during a loop
Use [page:Object3D.lookAt] for typical real-time mesh usage.
Neither bounding boxes or bounding spheres are computed by default. They need to be explicitly computed,
otherwise they are *null*.
