warp.sample\_unit\_cube
=======================

.. function:: warp._src.lang.sample_unit_cube(state: uint32) -> vec3f

   .. hlist::
      :columns: 8

      * Kernel
      * Python

   Uniformly sample a point in the unit cube ``[-0.5, 0.5)^3``, centered at the origin.
   
   Returns a ``vec3``. In a kernel, advances ``state`` in
   place; called from the Python scope, it does not modify ``state``, so repeated
   calls with the same ``state`` return the same point (see :func:`rand_init`).
