warp.mesh\_eval\_velocity
=========================

.. function:: warp._src.lang.mesh_eval_velocity(id: uint64, face: int32, bary_u: float32, bary_v: float32) -> vec3f

   .. hlist::
      :columns: 8

      * Kernel
      * Differentiable

   Evaluate the velocity on the :class:`warp.Mesh` given a face index and barycentric coordinates.
