R help - Feb 2010 - Using contour3d: axes, plotting to file, with lattice

I am looking for examples of how to plot with contour3d() to a PNG or PDF file,
add axes and other elements to the isosurface plot, and use contour3d in
conjunction with lattice.  Regarding lattice, I'm not necessarily looking
for conditioning on the data shown in the isosurface plots, just a way to show
multiple plots in one figure and label them.  I am new to the packages misc3d
and rgl.

Thanks,

You can't really combine rgl with lattice:  rgl uses a completely 
different graphics system.  (This might be wrong if lattice can import a 
bitmap, but that would be the only way to get rgl material into lattice.) 

To add axes and other stuff, read the rgl man pages.  There are 
functions axis3d, points3d, etc., that can add things to rgl plots. 

It's also possible in misc3d to output to static displays using either 
static or grid graphics; the latter would be combinable with lattice, 
but I've never used it.  I think it would be harder to add elements, 
since doing 3d graphics in a 2d system requires all sorts of ordering 
tricks, and you really need low level access.

To output rgl displays to PNG files, use rgl.snapshot.

Some of the examples in the JSS paper http://www.jstatsoft.org/v28/i01
might be useful for integrating contour3d results with lattice.
