Detailed Description

The btBroadphaseInterface class provides an interface to detect aabb-overlapping object pairs.

Some implementations for this broadphase interface include btAxisSweep3, bt32BitAxisSweep3 and btDbvtBroadphase. The actual overlapping pair management, storage, adding and removing of pairs is dealt by the btOverlappingPairCache class.
