You feed it cross-sections, I assume (not having used the program.)
For the Tootsie pop, you'd feed it a bunch of identical images with
small circles (for the stick) and then a series of circles getting
larger and larger, then reducing again to nothing (for the candy).

Picture what one of those egg-slicer gadgets you can get at the local 
kitchen store would do to your lollipop, and you'll have a pretty good
idea what you need.  Or, if you wanted to make a file for a human, try 
this URL for a (somewhat graphic) depiction of cross-sections:
