Terminology for Vertex is not clear and missing.

Having used 3D packages such as 3D Studio 4.0 I am used to thinking of a vertex as a coordinate x,y,z.

However UBER H3 library seems to use the term for an H3 Vertex as far as I can tell.

So basically a H3 Index repurposed for a H3 Vertex Index.

This API documentation mentions verteces/vertexes however it's not immediately clear if a vertex in the sense of 3D coordinate is ment or vertex in the sense of an H3 Index... H3 Vertex Index.

https://h3geo.org/docs/api/vertex

Also the H3 Terminology makes no mention of the word/term Vertex or the difference between Vertex in the 3D coordinate sense of the H3 Vertex Index sense.

https://h3geo.org/docs/library/terminology

It would be a good idea to update the documentation to more clearly explain the difference.

(
Perhaps the same could be done to indicate a cleared difference between an edge between 3D verteces and an edge index between H3 Indexes. Though I am not yet familiar unknown with H3 Edges and H3 Edge Indexes and such... I am still trying to figure this part out :)

Also I have not yet used the H3 Vertex Index functionality... but from the looks of it... I think what I am writing about is correct.

Start with the API vertex documentation at h3geo.org/docs/api/vertex and the terminology page at h3geo.org/docs/library/terminology. Clarify that an H3 vertex is an H3 Vertex Index rather than a 3D coordinate, and define the related vertex and edge terminology where appropriate. Done means the distinction is clear on both documentation pages.
