  • How to efficiently integrate 3D assets in a pipeline composed of different 3D software ?


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). 1.

Collab DreamWorks Animation & SideFX

Houdini Cloud FX

The new Cloud FX tools offer an artist-friendly way of building, sculpting and rendering cloud formations. This workflow utilizes sparse volume sculpting tools created as part of the OpenVDB open source initiative. The integration of these tools is the result of a direct collaboration between DreamWorks Animation and Side Effects Software.
