Detailed Description

A callback object called each time a Sector becomes visible through a Portal.

Note: a callback can be called multiple times with the same Sector argument if a Sector is discovered multiple times through different portals. Using callbacks can be very useful to perform special actions upon sector discovery, like enabling/disabling animations, enabling/disabling a ActorKdTree scene manager or a Terrain scene manager to render the external environment etc.
