Portals and Line of Sight...

Would anyone be able to point me in the right direction in the SDK to look at and learn how Line of Sight figures into whether a portal is active or not?
It seems that only the geometry attached to the interior of which a given portal is attached will block the Line of Sight to the portal. This effectively means that a portal between the outside and inside of an interior is active unless you move to a position where that interior's geometry blocks it. Other interiors, and DTS objects, do not affect it.
The idea here is to only render the zone if the player can *actually* see into it. And prevent it otherwise, such as with a door being closed, or other buildings being in the way in large city areas.
