Detailed Description
An axis-aligned bounding box (AABB) is a non-rotatable rectangle always aligned to the axis. It is defined by a center point and a half-width vector representing the extent of each of the axes. Its main purpose is to encapsulate another geometry object, preferably a rotatable one of higher complexity.
