That's not really easy to do well using the "painter's
algorithm" that
persp uses. It needs to know all the facets of both surfaces so it can
sort them from back to front for display.

You can display two surfaces using the persp3d function in the
unreleased next version of rgl (build your own from the source at
http://rgl.neoscientists.org, or get a prebuilt copy from my web page
http://www.stats.uwo.ca/faculty/murdoch/software), or put together your
own using rgl.surface in the current version.
