Right! But there is no mesh! That's the problem. How do I get that mesh?
There's only 2D pictures with POV turning it into something that looks like
a mesh.
I'm talking about outputting a mesh. Remember what I said about turning
isosurfaces into meshes.

Great... but is there a way to output a mesh?
There should be... and POV should read compressed mesh files without having
to go through a macro.
