"df3 density" would help your quest.

df3 files are a binary description of a 3D cube split in voxel (smaller
cube): for each voxel, the relative density (0 to 255 for a 8 bits file)

You can find one example in include/spiral.df3 (used by
scenes/interior/media/galaxy.pov )

About generating your own df3 files, it depends on the source of your
data. Some people use 3D sampling of modelled meshes in other programs
to get them.
