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.
