.. _class_Vector3:

Vector3
=======

Vector used for 3D math.

.. rst-class:: classref-introduction-group

Description
-----------

3-element structure that can be used to represent positions in 3D space or any other triplet of numeric values.

\ **Note:** In a boolean context, a Vector3 will evaluate to ``false`` if it's equal to ``Vector3(0, 0, 0)``. Otherwise, a Vector3 will always evaluate to ``true``.
