How making an 3D Widget always visible (even inside a object)

Hi guys, i have a question: is possible to a 3d widget be always visible?

example:

This is what i want: http://imgur.com/a/fS29l

This is what really happens when the widget get inside a object or terrain: http://imgur.com/xLHCG29

The goal is making this widget a 3D status bar (health, ammo e etc) so the text cant get inside de terrain or any other mesh.
