One way would be to use the symbols() function with scatterplot3d(), if
symbols() is sufficient to show the other properties.

A more complicated way would be to write the individual plots to .png
files, and then use sprites3d() in rgl to plot those pictures at the
point locations.  (These are 2d sprites, not 3d sprites.) I'm not sure
how good it would look:  sprites tend to look blurry because of all the
resizing that takes place.
