No, what I think he really wants to be able to do is to say

plot, X, Y, Z

where (X(i), Y(i), Z(i)) represents a point in 3D space. (One would have to
define a viewing angle, of course.) Sounds like a reasonable idea to me.
Unfortunately, I don't think IDL can do this at the moment, at least not so
straightforwardly.
