[R] rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7
Hello,
As an example, I ran the following code:
library("rgl")
example(plot3d)
rgl.snapshot("test.png")
The full plot is visible in the window titled RGL device 1 [Focus], but only a
small portion of the upper left part of the plot is visible in test.png (see
attached test.png, if the list server attaches it. Otherwise, email me if you
like and I'll send it directly to you.)
The output of sessionInfo() is as follows:
R version 3.2.3 (2015-12-10)
Platform: x86_64-pc-linux-gnu (64-bit)
Running under: CentOS Linux 7 (Core)
locale:
[1] LC_CTYPE=en_US.utf8 LC_NUMERIC=C
[3] LC_TIME=en_US.utf8 LC_COLLATE=en_US.utf8
[5] LC_MONETARY=en_US.utf8 LC_MESSAGES=en_US.utf8
[7] LC_PAPER=en_US.utf8 LC_NAME=C
[9] LC_ADDRESS=C LC_TELEPHONE=C
[11] LC_MEASUREMENT=en_US.utf8 LC_IDENTIFICATION=C
attached base packages:
[1] stats graphics grDevices utils datasets methods base
other attached packages:
[1] rgl_0.95.1441
loaded via a namespace (and not attached):
[1] tools_3.2.3
In addition to the CentOS 7 machine, I have a CentOS 5.3 machine, which has R
3.0.2 and rgl 0.93.996. I tried the code above on it and it captured the full
window in the output of rgl.snapshot (i.e., it worked properly).
To see whether the difference could be attributed to the CentOS version or the
R/rgl version, I put R 3.0.2 with rgl 0.93.996 on the CentOS 7 machine and ran
the code above. As with the earlier CentOS 7 run, only a small portion of the
plot was visible in the output of rgl.snapshot. So it seems the difference is
due to a difference in the CentOS versions and not the R/rgl versions.
Thanks in advance for any help.

[R-sig-Fedora] rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7
Dear R-SIG-Fedora, I'm finding that on CentOS 7, rgl.snapshot (a function in the R package rgl, which provides an R interface to the OpenGL 3-d graphics library) only captures a small portion what's visible in the RGL device window. This does not happen with the same R and rgl versions on CentOS 5.3 (see details below). The maintainer of rgl, Duncan Murdoch, responded (see below) that the rgl code has not changed in a long time, so it's likely, although not certain, that the problem lies with CentOS 7. I know very little about graphics, but it seems to me from looking at the rgl source code that the fundamental work of rgl.snapshot is done by calls to glReadBuffer, glPixelStorei, and glReadPixels, which seem to be functions in the OpenGL library. Can anyone take a look at this or advise me on how to proceed? Thanks very much in advance. -Ben -----Original Message----- From: Duncan Murdoch [mailto:murdoch.duncan at gmail.com] Sent: Friday, January 08, 2016 8:13 PM To: Wittner, Ben, Ph.D.; r-help at r-project.org Subject: Re: [R] rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7 On 08/01/2016 4:13 PM, Wittner, Ben, Ph.D. wrote:> Hello, > > As an example, I ran the following code: > > library("rgl") > example(plot3d) > rgl.snapshot("test.png") > > The full plot is visible in the window titled RGL device 1 [Focus], > but only a small portion of the upper left part of the plot is visible > in test.png (see attached test.png, if the list server attaches it. > Otherwise, email me if you like and I'll send it directly to you.) > > The output of sessionInfo() is as follows: > > R version 3.2.3 (2015-12-10) > Platform: x86_64-pc-linux-gnu (64-bit) Running under: CentOS Linux 7 > (Core) > > locale: > [1] LC_CTYPE=en_US.utf8 LC_NUMERIC=C > [3] LC_TIME=en_US.utf8 LC_COLLATE=en_US.utf8 > [5] LC_MONETARY=en_US.utf8 LC_MESSAGES=en_US.utf8 > [7] LC_PAPER=en_US.utf8 LC_NAME=C > [9] LC_ADDRESS=C LC_TELEPHONE=C > [11] LC_MEASUREMENT=en_US.utf8 LC_IDENTIFICATION=C > > attached base packages: > [1] stats graphics grDevices utils datasets methods base > > other attached packages: > [1] rgl_0.95.1441 > > loaded via a namespace (and not attached): > [1] tools_3.2.3 > > In addition to the CentOS 7 machine, I have a CentOS 5.3 machine, which has R 3.0.2 and rgl 0.93.996.

[R] rgl.snapshot only captures a small portion what's visible in the RGL device window on CentOS 7
The problem discussed below was fixed on my computer with much help from Tom
Callaway, of RedHat.
My computer has an NVIDIA graphics card and CentOS 7 comes with an open-source
driver for NVIDIA graphic cards called nouveau. When I replaced the nouveau
driver with a driver from NVIDIA, the problem went away.
To see whether your machine has an NVIDIA graphics card, execute the command
lspci -v
and search in the output for VGA. The top of that block of output will tell you
what graphics card you have and the last line of the block will tell you what
driver is in use.
In my case the top of that block of output was the following:
07:00.0 VGA compatible controller: NVIDIA Corporation G84GL [Quadro FX 370] (rev
a1)
So I knew I had an NVIDIA graphics card and that the model was Quadro FX 370,
which was important when trying to determine which driver to download from
http://www.nvidia.com/object/unix.html .
After downloading the driver, I was not able to get it installed just using the
instructions from the NVIDIA download page. The key for me was to follow the
instructions in http://www.dedoimedo.com/computers/centos-7-nvidia.html .
Good luck!
