Well, there is a function that can determine if a point is inside an object
or not.  That would work for most but not all objects.  Determining the
color of an object at just about any position should be possible as well,
also it would not be perfect (given that usually nobody assigns interiors to
solid objects and one would have to use the texture an artist only assumed
would be used for the outside - nevertheless, as most textures are defined
at any point in space, it would still be possible to make up a color for
those invisible voxels as well).

Which leaves the compression.  I never implemented any wavelet based
compression, but from what I have read, those are usually a bit more complex
than a simple JPEG or PNG/ZIP compressor to implement.  So unless someone
has a library for this, I would assume implementing the code for the
compression would take by far most of the time.
