You can compute the exact offset of a polygon or an approximation using CGAL::offset_polygon_2() or CGAL::approximated_offset_2(), respectively. Your problem is similar. The difference is that your polygons degenerate to polylines. I haven't tried it out, but conceptually you should be able to use the functions above. If it doesn't work, let us know, and we might be able to make it work.

Hi,

Is there a way to get the Minowski sum for a two-D path and a circular disc?
I would like the result to be a two-D polygon.  Or is there another way to
do this?  (Without using Minowski sum?)

Here are some picture examples.  (My input would be the centerlines [and a
disc width].  The output would be the boundary.)
