a year or so ago I brought up (I can't remember exactly
with who or where) the possibility of contributing a concave
hull algorithm and the good news is that I'm close to
convincing my work to open-source an implementation I wrote.
To justify additional effort in preparing the code for
release, they (senior leads) want to confirm that other people
actually want it. I think that's hard for other people to give
without seeing the actual code, but what I'm hoping for from
the maintainers is just a non-binding "yes" that, in
principle, you would be interested in an implementation of the
concave hull algorithm described in the following paper:
There would be no obligation for you to accept or take
custody of the code (obviously), they just want to know that
we're not wasting our time preparing it. I originally wrote it
with contribution in mind, so I really just need to do some
polishing, make it respectable, etc.
