Optional constructor, accepts position and size.

.. _class_AABB_method_encloses:

- :ref:`bool<class_bool>` **encloses** **(** :ref:`AABB<class_AABB>` with **)**

Returns ``true`` if this ``AABB`` completely encloses another one.

.. _class_AABB_method_expand:

- :ref:`AABB<class_AABB>` **expand** **(** :ref:`Vector3<class_Vector3>` to_point **)**

Returns this ``AABB`` expanded to include a given point.

.. _class_AABB_method_get_area:

- :ref:`float<class_float>` **get_area** **(** **)**

Gets the area of the ``AABB``.

.. _class_AABB_method_get_endpoint:

- :ref:`Vector3<class_Vector3>` **get_endpoint** **(** :ref:`int<class_int>` idx **)**

Gets the position of the 8 endpoints of the ``AABB`` in space.

.. _class_AABB_method_get_longest_axis:

- :ref:`Vector3<class_Vector3>` **get_longest_axis** **(** **)**
