I guess you mean "automatically", right ?

you can try to have a look at the capability of crossroads (Windows 95
to Windows 2000)

http://animatricity.com/pages/downloads/3d_apps/crossroads.htm

The homepage for the developper is lost in limbo, but the provided url
provide a downloadable zip. Assumes your own risk about it (I do not
have windows)

The syntax of povray for sphere and cylinder is stable enough that it
might be supported, even on current output of avogadro.

Short of that, and unless someone provide a different answer, I would
refer you to the knowledge base

http://wiki.povray.org/content/Knowledgebase:Files_and_formats#Topic_2

There is echo of 3D23D program, but I have no link for it (seems lost
too).

A request on Avogradro (#248) is opened since 2012 for export in
obj/mtl, maybe you can contribute to it.

The irony of it: After Effects is a "software as a service" license, I
could suggest to ask an evolution to Adobe (might not be free).

On the other side, there is derivative of povray which might export as
gts (Gnu Triangulated Surface library) or STL (STereoLithography)
format, from imperfectly meshified finite 3D objects.
Then it would be another story to find a converter to obj for one of the
m.
