include examples. The 3D examples related to the misc3d packages are
also available in
http://www.stat.uiowa.edu/~luke/R/misc3d/misc3d-pdf/. At some point
the code there will be added to misc3d. It should be possible to
adapt these ideas to other objects rendered with rgl.

Luke,
Your misc3d-pdf example is very instructive and the .tex file shows how
to embed in LaTeX. Thanks! (JCGS 19(1) is actually one of the nicest
issues in a long time.)
Of the two approaches you
describe, the Asymptote route seems easier and more capable than the
MeshLab one.
The Asymptote/PRC route was the only one I could find (with a limited
amoutn of time and effort I could put in) that would support both
color and transparency. The downside is that PRC suport requires very
new Adobe readers and seems to result in huge files. I know the U3D
format support color but MeshLab doesn't seem to put color into its
U3D exports. I forget whether U3D supports transparency. Someone with
the energy and motivation to do so can read the binary file format
specs and write these file formats directly usign alltheir
cababilities, but I wasn't up to doing that at the time.
It would be particularly useful to have this capability available for rgl.
Any plans for this?
Not on my part. misc3d scenes are very simple -- just triangular mesh
objects with optional color or transparency. rgl handles much richer
scenes so figuring out how to translate such scenes to one of the
binary formats would be a lot more work. On the other hand it may
already have been done in the OpenGL community.
One note: With Adobe Acrobat Pro 9.3.1, the U3D and PRC images display
on screen, but do not print (replaced by the filename). Is this your
experience too?
I believe so. There may well be a way of including a static image in
the LaTeX that would be used by printing and readers that don't
understand the embedded formats, but I haven't had the chance to check
the movie15 documentation for that.
