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.

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.
