Big wish here but not an unrealistic one.
Please add vdb file support in Rhino, I think it would be great to have especially in Grasshopper. It would be useful to add Daniel Pikers and Ghs abilities to create and edit vdb files since Gh already supports voxels.
I think it is doable and would add yet another feather in Rhinos cap. This would open up a link to particle systems via rendering and could be added to our Rhino renders to do amazing volumetric effects.
Imagine being able to generate cloud patterns tornados sand storms and send them out to Vray or other rendering systems as well as smoke and explosions etc. I think Gh has all the capabilities to interface in a number of ways.
For those of you wondering:
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).
