I am looking for an algorithm that can determine if a 3D object will be hidden
by other object drawn later.  In other words, I am trying to find a way
to avoid drawing a complicated object that will be covered up anyway.  Can 
someone either mail me an algorithm , some  code (Fortran or C) or give me references to books and/or articles.  Thanks in advance.
