I've found some non-CRAN packages that link to it but nothing that seems to
provide access to all CGAL functions (listed below). Any ideas if there are
plans afoot for this or even if it's worth doing?
There is a lot you can do with a constrained triangulation, it's a "hammer"
and sometimes overkill but it's extremely flexible and powerful. I'm happy
to flesh out examples for problems you think might be solvable with it to
help promote why CGAL would be useful in R.
I'm very interested in general forms for these data, and the idea is to put
all the 3D rangl stuff on this footing eventually:
tidygraph is a very good example of how we can modernize these indexed data
structures, and other newish packages icosa, webglobe, dggridR, also touch
on this "mesh" way of working. For that matter spdep and GEOS work that way
internally, but we only have fragments of the concept available at an R
Simon Urbanek has s-u/rcgal on github but it doesn't expose very much.
