Detailed Description

This class represents a bounding volume of type "Axis Aligned Bounding Box".

It's a box where all the edges are always aligned with the world coordinate system. The AABB is defined by the minimum and maximum world coordinates of the three axis.

Return true if the current AABB is overlapping with the AABB in argument.

Two AABBs overlap if they overlap in the three x, y and z axis at the same time.
