Description
VDB is more or less standard for volumetric data: it's supported by Blender and there is good tooling around it. And it looks like you already have a GPU voxelizer, which is the hard part.
VDB has two formats, in fact: the regular density+color grids, and the point cloud format, which is a grid where voxels store pointers to the attached list of points. I'm mainly interested in the density+color grid, as it's supported by Blender.

Research direction
The issue names no files, tests, or entry points. Start by locating the existing GPU voxelizer and format-conversion entry points, then investigate OpenVDB's density and color grid requirements; done means supporting the regular density+color format, with point-cloud support not required by this request.
