Issue with rgl.spheres and spheres3d

[uwemenzel]

Hi, thank you very much for providing the rgl package. While many things work perfectly for me, I unfortunately also encountered some issues. I do not suceed plotting spheres using the package. For example, I use the code snippet rgl.open() # Open a new RGL device rgl.bg(color = "white") # Setup the background color rgl.spheres(x, y, z, r = 0.2, color = "grey") taken from http://www.sthda.com/english/wiki/a-complete-guide-to-3d-visualization-device-system-in-r-r-software-and-data-visualization

I can open the window and I can change the background to white. But the rgl.spheres command just does not do anything. I also noticed that there is no description of rgl.spheres in the documentation. The same is valid for spheres3d. It just does not plot anything, and no error messages appears. I have updated the package and all dependencies by running install.packages("rgl", dep = TRUE), which worked without problems. I'm using RStudio 2022.12.0 Build 353 with "R version 4.2.2 (2022-10-31 ucrt)" on Windows10. AMD Ryzen 7 5700U with Radeon Graphics 64-bit operating system, x64-based processor 16,0 GB (15,4 GB usable) rgl version ‘0.110.2’ Any help is appreciated!

You shouldn't be using the obsolete functions rgl.open, rgl.bg or rgl.spheres. The web page you link to is quite out of date, but I don't see a way to leave a comment for the author. If you know one, could you please pass on this message to them?

The supported way to do those steps is to run

open3d() # Open a new RGL device
# bg3d(color = "white") # white is the default, you don't need this
spheres3d(x, y, z, r = 0.2, color = "grey")

open3d() # Open a new RGL device spheres3d(x, y, z, r = 0.2, color = "grey")

Thanks a lot, Duncan, for the quick answer. However, even with the code above (and specifying x,y,z before), I have the same issue. (I tried this before, even in the usual Windows R environment in order to exclude that this is an RStudio issue). I'm really sorry to say that ..

I think you'll need to show me x, y, and z then so I have reproducible example.

Hi,

for example:

library(rgl) open3d() # Open a new RGL device x = rnorm(5) y = 3rnorm(5,2) z = 2rnorm(5,2) spheres3d(x, y, z, r = 0.2, color = "grey")

Best, Uwe

That works fine for me. Please try installing the devel version using

remotes::install_github("dmurdoch/rgl")

It should appear on CRAN in a week or two. If that's not enough to fix the issue, it might be a problem specific to your hardware. As a workaround, you should still be able to use rglwidget() to have things display in a browser or the RStudio Viewer window instead.

Okay, thanks!! Best, Uwe

I am closing this now, as I couldn't reproduce it. If it is still happening or starts again, please comment here and reopen it.

Okay, thanks!
