Broad-Phase collision detection

An axis aligned bounding box (AABB) for a PhysX object is the smallest box that can enclose that object provided the box edges are always parallel to the coordinate axes. The AABB of an object never rotates, although the object itself can rotate in any axis.

Broad-Phase collision detection

AABB (axis aligned bounding box) of a heart shaped object

If the AABB of two objects are not overlapping or colliding with each other, under no circumstances objects of AABB can collide with each other. On the other hand if AABB of two objects are overlapping/colliding, collision between actual objects can happen but it's not guaranteed. Checking collision using ...
