Note also that there are cases in which results will be very dependent on `alpha`, and others in which there is no sensitivity whatsoever, and results will remain identical regardless...

Cool, thanks heaps, I hadn't seen concaveman at all, so will definitely incorporate that in my stuff. Also great to see that tweet, because I've also been thinking some kind...

Hey, the paper behind "concaveman" is really cool, and very trivial to implement. Shall we just implement our own C++/C version for general `hypertidy` usage? It'd be pretty trivial and...

Oh, really?

Okay, so I had a read through the `alphahull` code, and it seems actually perfectly satisfactory. The main triangulation is done in (copied) fortran, so re-writing from scratch is not...

Other approaches to concave hulls [here](http://www.it.uu.se/edu/course/homepage/projektTDB/ht13/project10/Project-10-report.pdf) and [here](https://arxiv.org/pdf/1309.7829.pdf). Lots of approaches. One idea would be to implement at least one, ideally (effectively) parameter-free concave hull generator as part of `decido`...

wow, that last link provide some deep stuff to ponder :metal: Edit: Note the quote (me on my fave trope again): "it panics when intersecting everything results in two distinct...

That is so cool!

To avoid opening a new issue, may I request another extension of `PointInPolygon`, via vectorization of polygons to return a matrix of `[npoints, npolygons]` (or the other way around)? I...

I'm working on resolving that within the dashboard. Airtable will be the primary status, and slack will feed through to that in one direction only. Docs won't be updated until...
