Error in hillshade[, , 1] * scales::rescale(shadowmap, c(max_darken, 1)) - again

gsapijaszko commented 2 years ago

Hi, facing a strange issue:

running the script/examples in RStudio:

elmat %>%
  sphere_shade(texture = "desert") %>%
  add_water(detect_water(elmat), color = "desert") %>%
  add_shadow(ray_shade(elmat), 0.5) %>%
  plot_map()

receiving the error:

Error in hillshade[, , 1] * scales::rescale(shadowmap, c(max_darken, 1)) :                                               
  non-conformable arrays

without any output in Plots tab.

However when I tried to prepare an reprex, I got quite expected response:

library(rayshader)

#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 = raster_to_matrix(localtif)

#And we can add a raytraced layer from that sun direction as well:
elmat %>%
  sphere_shade(texture = "desert") %>%
  add_water(detect_water(elmat), color = "desert") %>%
  plot_map()

elmat %>%
  sphere_shade(texture = "desert") %>%
  add_water(detect_water(elmat), color = "desert") %>%
  add_shadow(ray_shade(elmat), 0.5) %>%
  plot_map()

^{Created on 2022-05-17 by the reprex package (v2.0.1)}

which looks good. Is there any missing step/config which I shall process to get it working in script/console?

Regards, Grzegorz

I've been dealing with the same error today, but I finally solved it. I tried remotes::install_github(), but no dice. Then after messing around some more, I tried reinstalling from github again, this time updating rayimage as well -- that did the trick.
