[Freegis-list] OT: Voronoi

Hmmm, may be I will have asked a better question if I knew
what it is.

I have seen many GIS applications in the forum, and on the freegis.org
pages.
However, I am yet to find one which really uses the Voronoi algorithm. I
came
across this while reading the "dying" GFC library, and wishes to know more.
In fact, neither OpenEV, MapServer etc are using it so by your write up you
do not consider these are GIS applications?

Please, I really need the help - which open source systems are using this
algorithm
so that I could find out more?

Best regards,
Paul.
