Download and build hmm: https://github.com/fogleman/hmm

Create a heightmap:

png::writePNG(volcano, "a.png")

Convert to STL:

bin/release/hmm a.png output.stl

Read in R and plot

d <- rgl::readSTL("output.stl", plot = FALSE)
 rgl::triangles3d(d, col = colourvalues::colour_values(d[,3]))
## rglwidget()

Densify the coordinates, build mesh3d etc. ...

library(dplyr)
as_tibble(d) %>% distinct()  ## 516 rows (not 3000)
