stla/tessellation

Delaunay and Voronoï tessellations with R, with emphasis on the 3D case.

To install the development version, run:

remotes::install_github("stla/tessellation", dependencies = TRUE)

I did a vignette but it was too big for the CRAN submission. So I used pkgdown, and you can find the vignette here.

Request for area and volume calculations

It is possible to include an output for the surface area and volume of the convex 3D hull of a Voronoi cell? That could be very useful, for example, in astronomy, where the inverse of the Voronoi cell volume is a proxy for the local density.

Thanks.

Possible to replace `randomcoloR` with some analogue or make it optional?

randomcoloR pulls in dependency on V8, which is a) a very heavy stuff to build and b) broken on some platforms.
