Hi All,

I have an inexorable tendency to do analyses with POV-Ray, perhaps because it's
the first scripting language I groked.

Anyway, I've been playing with 2-D Voronoi polygons using 3-D pov cones to
derive medial axes of complex shapes (e.g.
http://smathermather.wordpress.com/category/optics/pov-ray/ ).  I like the speed
and outcomes that I'm getting, but I wondered if there's a trivial (or
otherwise) way to render the boundaries of the cones which create the medial
axes as something vectorized from within POV-Ray.  Thoughts?

Thanks,
Best,
Steve
