What Rich said will work. Here are some details to think about:
There are two ways that snapshot3d works. The original way takes a
snapshot from your screen. That will produce an image the same as what
you see, at the same resolution. You get this mode if you set "webshot
= FALSE", or if you don't have the webshot2 package installed.
The newer way uses the webshot2 package. Unfortunately that package is
not on CRAN, so you'd need to install it using
remotes::install_github("rstudio/webshot2") . It requires that you have
the Chrome browser installed (or supposedly some other browser providing
the same libraries; I don't know what else will work).
The webshot2 package doesn't need to display on your screen, so in
theory you can produce larger snapshots. It can also do a better
version of rendering: the rgl window uses OpenGL 1.x methods, while
webshot2 uses WebGL, which is based on a newer OpenGL version. I find
the font support to be better, and there are some improvements to
shading of surfaces. On the negative side, it can be much slower,
especially on a complex scene, and occasionally has different bugs than
the other display.
Finally, you don't need to use your mouse to change the window size; you
can specify width and height in the snapshot3d() call, and the window
will change as requested.

you can make the rgl window full screen, and then stretch the graph to
fill the window, and then use snapshot 3d

Ducan,
As always, you are very giving of your time to help R users. Thank you!
scatter3d is from the car package.
As I understand snapshot3d, it takes a screen shot and saves the
resultant file. This implies that the resultant file will be 72 DPI. I
need to get a higher resolution image, at least 300 DPI. Do you have any
suggestions?
Thanks as always.
John

I am trying to create a 3-D graph (using scatter3d) and save the graph to a file so I can insert the graph into a manuscript. I am able to create the graph. When I run the code below an RGL window opens that has the graph. The file is saved to disk after dev.odd() runs. Unfortunately, when I open the saved file, all I see
is a white window. Can someone tell me how to have the file so I can
subsequently read and place the file in a paper? The problem occurs
regardless of the format in which I try to save the file, e.g. png, tiff.
x <- 1:10
y <- 2:11
z <- y+rnorm(10)
ForGraph<-data.frame(x=x,y=y,z=z)
ForGraph
gpathj <- file.path("C:","LAL","test.jpeg")
gpathj
jpeg(file = gpathj)
par(mai = c(0.5, 0.5, 0.5, 0.5))
scatter3d(z=ForGraph$x,
y=ForGraph$y,
x=ForGraph$z,
surface=FALSE,grid=TRUE,sphere.size=4
,xlab="Categories",ylab="ScoreRange",
zlab="VTE Rate (%)",axis.ticks=TRUE)
dev.off()
You didn't say what package you found scatter3d in, but you did say it
opens an rgl window. rgl doesn't use R graphics devices, so jpeg() and
the like don't work.
To save an rgl image, you use the rgl::snapshot3d() function. It only
has support for saving to PNG format.
If you are writing your manuscript in R Markdown or knitr Rnw, there are
ways to have the file included automatically. There have been methods
to use with Sweave as well, but those aren't being maintained: people
should use knitr instead.
