Please add a VDB writer

From a user (Chris G.) VDB is an export standard which Houdini can read in.

http://www.openvdb.org/ 1

Export of .geo format data only works for polygons. What we want to do is export volumetric data in VDB format so that we can perform volumetric post-processing in Houdini. There is a package called Redshift which allows you to perform volumetric rendering of VDB data in Houdini using the GPU. Render times per frame have been shown to go down from 1 hour to 2 minutes.

From my perspective, this is a pretty big WOW.

So, my questions:

Does it make sense to add this writer into ParaView? How hard would it be? Can we get it in for the 5.7 release?

Reply from Utkarsh:

It’s doable for sure. We’d need a bit more exhaustive investigation to see how complicated it could be, but shouldn’t be too hard esp. if we can start with a small set of use-cases to support in the first pass.

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
