no rgl window and other issues

[martin473]

When I run this code it wont render. I tried reinstalling everything. Rayrender I reinstalled from install.packages. Everything else I installed from the github command.

>   library(rayvista)

+                           elevation_detail = 14, overlay_detail = 16)

((There are 50 of these warning messages and they are all exactly the same))

When I run this it renders completely fine, opens up an rgl window and everything

library(rayshader)
library(dplyr)
library(rgdal)

#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)

elmat %>%
  sphere_shade(texture = "desert") %>%
  #add_water(detect_water(elmat), color = "desert") %>%
  add_shadow(ray_shade(elmat, zscale = 3), 0.5) %>%
  add_shadow(ambient_shade(elmat), 0) %>%
  plot_3d(elmat, zscale = 10, fov = 0, theta = 135, zoom = 0.75, water = TRUE, waterdepth = 100, wateralpha = 0.5, watercolor = "lightblue", waterlinecolor = "white", waterlinealpha = 0.5, phi = 45, windowsize = c(1000, 800))

Hi Martin, This looks like a rayvista issue rather than rayshader - perhaps better to file here: https://github.com/h-a-graham/rayvista/issues However, I can't reproduce this error and the above code is working for me. I suspect this is due to another outdated package. Have you recently installed rayvista as follows: devtools::install_github("h-a-graham/rayvista", dependencies=TRUE) This should make sure that a recent version of {rgdal} is installed. That warning message however, may be being thrown by {terra}. Can you try updating both {terra} and {rgdal} and then see what happens? Thanks
