Welcome


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 was developed by DreamWorks Animation for use in volumetric applications typically encountered in feature film production and is now maintained by the Academy Software Foundation (ASWF).

OpenVDB is the first project to be hosted by the recently launched Academy Software Foundation. The ASWF will maintain and further develop the project with oversight provided by a Technical Steering Committee (TSC). Developers interested in learning more or contributing to OpenVDB can sign up to join the mailing list at www.aswf.io/community.

Note that the OpenVDB GitHub repository is now hosted by the ASWF at github.com/AcademySoftwareFoundation/openvdb. Links to the old repository at dreamworksanimation/openvdb will automatically redirect, but consider updating your local clones with a command like “git remote set-url origin https://github.com/AcademySoftwareFoundation/openvdb.git”.
