Or try using persp3d() instead of rgl.surface()
Or follow the call to rgl.surface with a call to aspect3d.
(Actually, I generally recommend against using the rgl.* functions; it's
generally easier to use the *3d functions for the reasons described in
?r3d. The other version of rgl.surface is surface3d, which is more
primitive than persp3d. It would still show a flat surface, and the
aspect3d call would be needed. persp3d incorporates that.)
