warp.mesh\_get\_bvh

.. function:: warp._src.lang.mesh_get_bvh(id: uint64) -> uint64

   Return the identifier of a mesh's internal BVH.
   
   The returned id can be passed directly to the ``bvh_query_*`` builtins (:func:`bvh_query_aabb`,
   :func:`bvh_query_ray`, :func:`bvh_query_capsule`, :func:`bvh_query_sphere`) to run broad-phase
   bounding-volume queries against
   the mesh's triangle BVH; the bound indices they return are triangle (face) indices. Works for all
   BVH backends (including ``"cubql"``), since cuBQL meshes are converted to Warp's native BVH layout.
