warp.volume\_sample\_v
======================

.. function:: warp._src.lang.volume_sample_v(id: uint64, uvw: vec3f, sampling_mode: int32) -> vec3f

      * Differentiable

   Sample the vector (:class:`warp.vec3f`) volume given by ``id`` at the index-space point ``uvw``.
   
   ``uvw`` is in index space (voxel coordinates) and may be fractional; ``sampling_mode`` must be
   :attr:`warp.Volume.CLOSEST` or :attr:`warp.Volume.LINEAR` and is applied per component. Sampling
   uses the resolved volume value (see :func:`~warp.volume_sample`). ``id`` must identify a
   ``vec3f`` volume. In kernels, ``volume_sample_v()`` is equivalent to
   :func:`~warp.volume_sample` with ``dtype=warp.vec3f``.
   
   :returns: The sampled :class:`warp.vec3f` value.
   
   See :func:`~warp.volume_sample` for a usage example.
