.. _wrmath_api: Quick Overview ============== Namespaces ---------- All WNTRMUTE code is in the ``wr`` namespace. The ``geom`` class is used for code concerning itself with realspace, e.g. :ref:`Quaternions `. Coordinate systems ------------------ The library uses a left-hand coordinate system where +x is north, +y is east, and +z is up. Accordingly, where Euler angles are concerned, the ZYX (yaw / pitch / roll) axes are used. The code follows the convention of using ψ, θ, ϕ to represent yaw, pitch, and roll. Important classes ----------------- The foundational class of this library (and here's to a real mathematical workhorse) is the :class:`wr::geom::Vector` class. Other important classes are the :class:`wr::geom::Quaternion` class.
