I'm trying to render a VTK file containing a structured point data array into blender 3D. I've found an addon (BVTKnodes) allowing to import VTK files and extract iso surfaces from them, but here I would like to do a volumetric rendering.
Since blender can only handle OpenVDB files for volumetric input, I'm looking for a way to convert my VTK file into the OpenVDB format.
What would be the best option here ?
Thanks !
