It's a library with another approach, started independently, and they
came around the same time in Boost. However, there is Voronoi
functionality there:

Actually I don't know the current state of it, it was developed quite a
while ago during GSoC. But it, or parts of it, could be reused by us.

Besides that, both libraries are concept based.

Both is possible (because it is concept based, code can be shared).

Sure, there is a core-team working hard on Boost.Geometry, doing many
commits per week. But that is not always visible on the list. We target
specific long-term goals, so (at least that is for me the case) I cannot
dive into a mesh or tesselation library right now.
