.. function:: warp._src.lang.quaternion(dtype: Float) -> Quaternion[Float]

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Construct a quaternion.
   
   Zero-initialize the quaternion. Quaternions are laid out as
   ``[ix, iy, iz, r]``, where ``ix``, ``iy``, ``iz`` are the imaginary part, and ``r`` the real part.

.. function:: warp._src.lang.quaternion(x: Float, y: Float, z: Float, w: Float, dtype: Scalar) -> Quaternion[Float]
   :noindex:

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Construct a quaternion.
   
   Use the supplied components (type inferred from component type).

.. function:: warp._src.lang.quaternion(ijk: Vector[Float,Literal[3]], real: Float, dtype: Float) -> Quaternion[Float]
   :noindex:

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Construct a quaternion.
   
   Use the supplied vector/scalar (type inferred from scalar type).

.. function:: warp._src.lang.quaternion(quat: Quaternion[Float], dtype: Float) -> Quaternion[Float]
   :noindex:

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Construct a quaternion.
   
   Convert ``quat`` to the specified ``dtype``.
