The Java source code for the RepRap project has an STL slicer in (and
also a reasonably versatile area-fill algorithm). However, it is still
_very_ pre-release and under development. But it is fully GPLed and
open-source.

Go to:

     http://reprapdoc.voodoo.co.nz/bin/view/Main/Subversion

and check the

     https://svn.sourceforge.net/svnroot/reprap/trunk/reprap/host

section of the code out of the subversion SourceForge repository.

For details of the rest of the project, start at the second URL below.

Yours
