Detailed Description

Axis Aligned Bounding Box structure. (AABB)

A simple and efficient way to represent the boundaries of a 3D or 2D object for collision detection or spatial queries in game development and computer graphics. The sides of the bounding box are aligned with the coordinate axes (e.g., X, Y, and Z axes in 3D space). This means that the edges of the box do not rotate with the object but remain parallel to the axes. Bounding box defines a rectangular (2D) or cuboid (3D) volume that surrounds an object, used to approximate the object's shape for efficient calculations.
