AI_SDB_SpatialSector Class Reference
[Spatial Database]
#include <AI_SDB_SpatialSector.h>
Detailed Description
A collection of elements in a specific region of space.A sector represents a section of space with a bunch of objects in it. Note that the sector could be infinite in size, which is typically used for top or root-level sectors. Having finite-size sectors is encouraged where possible since it allows the spatial querying to work more efficiently.
You can query a sector with a AI_SDB_VisibilityVisitor or AI_SDB_SpatialVisitor, of which there are various types in order to perform different kinds of queries.
Sectors are typically connected to each other by portals. You can also nest sectors within each other using the NOH; a sector contains all the sectors that are child nodes of this sector.
