Only the Montereybay example will render

[dmcairns]

I am new to using rayshader, and I am having trouble getting any example except the Monterey bay example to render at all. For example, the following code does not render the 3d plot:

options(rgl.useNULL = FALSE,
        rgl.printRglwidget = TRUE)

library(rayshader)
library(rgl)

#Here, I load a map with the raster package.
loadzip = tempfile() 
download.file("https://tylermw.com/data/dem_01.tif.zip", loadzip)
localtif = raster::raster(unzip(loadzip, "dem_01.tif"))
unlink(loadzip)

#And convert it to a matrix:
elmat = matrix(raster::extract(localtif,raster::extent(localtif),buffer=1000),
               nrow=ncol(localtif),ncol=nrow(localtif))

ambmat = ambient_shade(elmat)

elmat %>%
  sphere_shade(texture = "desert") %>%
  add_water(detect_water(elmat), color="desert") %>%
  add_shadow(ray_shade(elmat,zscale=3,maxsearch = 300),0.5) %>%
  add_shadow(ambmat,0.5) %>%
  plot_3d(elmat,zscale=10,fov=0,theta=135,zoom=0.75,phi=45, background = 'white')

The following code, however, does render the 3D image in RStudio.

options(rgl.useNULL = TRUE ,
        rgl.printRglwidget = TRUE)

require(rayshader)
montereybay %>%
  sphere_shade(zscale = 10, texture = "imhof1") %>%
  add_shadow(ray_shade(montereybay, zscale = 50)) %>%
  add_shadow(ambient_shade(montereybay, zscale = 50)) %>%
  plot_3d(montereybay, zscale = 50, theta = -45, phi = 45, water = TRUE,
          windowsize = c(1000,800), zoom = 0.75, waterlinealpha = 0.3,
          wateralpha = 0.5, watercolor = "lightblue", waterlinecolor = "white") 

I am using RStudio 1.1.456 running on Mohave.

Any help with this will be appreciated. Thanks!

Does it open an rgl window? Are you running this locally on RStudio desktop, or RStudio server?

Your response gave me the clue that I needed to move forward with this. If I open XQuartz before starting RStudio, and open an rgl window with rgl.open() everything works fine. The rgl window is outside of the RStudio (desktop) environment that I am used to using. I still can’t get anything but the Monterrey Bay data to display in the Plots pane of the RStudio interface. Any thoughts on how to get that to show up in the RStudio Plots pane?

Thanks for your help!

There isn’t anything special about the Monterey Bay data—it’s simply a matrix. What happens when you replace montereybay with volcano in the examples?
