OpenVDB

DynaSkin, DynaBool and DynaCut rely heavily on OpenVDB to achieve their results.  OpenVDB is an Academy Award-winning, open-source C++ library comprising a novel hierarchical data structure and a suite of tools for the efficient manipulation of sparse, time-varying, volumetric data discretized on three-dimensional grids.  OpenVDB was originally developed at DreamWorks Animation, primarily by Ken Museth, Peter Cucka, Mihai Aldèn and David Hill.  It is now maintained by the Academy Software Foundation.  If you are interested in exploring more about OpenVDB, or would like to download the C++ library for your own use, please check out their website at http://openvdb.org , or their GitHub repository at https://github.com/AcademySoftwareFoundation/openvdb.
