Hello,

I'm new to Lisp, and was interested in finding a package that can
calculate two-dimensional simple concave polygon intersections and
areas.  Does anyone know of any that exist?

Best Regards,

Joshua

I think that McCLIM (http://www.cl-user.net/asp/libs/mcclim) should
contain some code for computing 2D polygon intersections.  I'm not
aware of anything else.
