Just plot both on the same graph. The cylinder3d function produces an
object which will be rendered as a cylinder (you need to call shade3d to
render it). There's no function for cones, but a cylinder with a very
small radius at one end would be close. You can't set the radius to
zero currently: it puts a bunch of points at the same position and gets
confused. Should probably fix that.
