@sgammon Interesting. We might have an odd case - we're using ESP as a unified API layer for multiple backend services on a single externally-facing domain. In this case, even...

This is a core H3 issue - at present, our `polyfill`/`polygon_to_cells` logic uses Cartesian polygons, not spherical polygons, so it's generally going to struggle with a polygon that contains a...

Yes, that was exactly the idea :). I have an example in JS here, but the rendering isn't great so you can't actually tell it's working: https://observablehq.com/@nrabinowitz/h3-polar-issues-with-polgon-to-cells The main thing...

I have a pretty good suspicion of the issue here. I think this is in the core library (I can repro in JS), and it's likely due to floating-point error...

The short answer is, not yet. We have added the `options` argument that will allow new modes without a breaking API change, but we haven't implemented different modes yet.

> I don't know if I want to endorse this "vcpkg" tool in the repo like this. [The H3 version it installs is several years out of date](https://github.com/microsoft/vcpkg/blob/master/ports/h3/portfile.cmake#L6) and it...

I think there's a valid issue here, which is that we use `vertex` somewhat interchangeably to talk about geographic vertexes (which are returned as part of `cellToBoundary`) and H3 Vertexes,...

H3 edges are given in direction order, which is based internally on IJK axes. They don't go around the cell in order. I believe the sequence is consistent, but there...

This is the visual aid I always use, possibly we should include this in the docs:

Each face is split into: - 4 base cells - 3 half base cells, where the other half is on the neighboring face - 3 fifths of a pentagon, where...
