Do you
want the same surface to be viewable in both directions? Or do you want to
look one way from one side and another way from the other
side?
If it
is the former, then just turn off backface culling in the attributes. If
you want to do the latter then have have two objects with the vertices wound in
opposite directions and then turn backface culling ON. Since from any one
vantage point you will be viewing either the back or front of a triangle, one or
the other will always show. If you don't do it this way there will be
z-buffer fighting for the difference surfaces.
