%global _description %{expand:
OpenVDB is an Academy Award-winning open-source C++ library comprising a novel
hierarchical data structure and a suite of tools for the efficient storage and
manipulation of sparse volumetric data discretized on three-dimensional grids.
It is developed and maintained by Academy Software Foundation for use in
volumetric applications typically encountered in feature film production.}
