====

|
|
|
Axis-Aligned Bounding Box.

|
|
Description
|
|
-----------
|
|
|
|
``AABB`` consists of a position, a size, and several utility functions. It is typically used for fast overlap tests.
|
|
|
|
It uses floating-point coordinates. The 2D counterpart to ``AABB`` is :ref:`Rect2<class_Rect2>`.
|
|
|
|
\ **Note:** Unlike :ref:`Rect2<class_Rect2>`, ``AABB`` does not have a variant that uses integer coordinates.
