Detailed Description
Any 3D map defines an arbitrary 3D region of space.
For efficient rendering and AI, this space must be recursively partitioned into subspaces. Any internet search for "Space Partitioning" will reveal popular and useful methods such as BSP trees, Octrees, kd trees, etc.
The aesop server doesn't care what partitioning strategy is used. All that is important is that the space is correctly partitioned into disjoint sets.
A Zone is a 3D region of space which (in general) completely contains a number of subzones, which contain subzones etc.
Zones are static. That is, for a given map, the zone structure does not change during gameplay. However, objects can move around in and between zones.
Zones should never be aware of drawing or rendering. Other code libraries can use Zone objects to draw.
