There are some 3D contributed packages available. Mine (djmrgl) has a
function called hist3d() that might do what you want. It's available
for Windows only from my web page
<http://www.stats.uwo.ca/faculty/murdoch/software> One of my projects
for the summer is to merge djmrgl with the other OpenGL project by
Daniel Adler; then (and possibly now) a cross-platform 3D histogram
will be available.
