DreamWorks animation tech goes open source

Rise of the Guardians ‘primary tools’ have now been released with an open source licence, allows for sparse volume processing

Announced nearly four months ago, 3D animation house Dreamworks, best known for movies like Shrek and How To Train Your Dragon, have finally released some of their code and tools in open source. OpenVDB is the result of this, and contains technology used in their latest film Rise of the Guardians.

The official website goes into more detail on what this is:

“OpenVDB is an 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 DreamWorks Animation for use in volumetric applications typically encountered in feature film production.”

Apparently, in Laymen’s terms, this means it handles smoke and other environmental features to make sure they properly fill the space.
