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.

)

const

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.
