Here's an example from "Practical IDL Programming" (p. 271). For
demonstration purposes, let's create a 2D sinc function defined over the
range -10 to 10 in x and y:

v = findgen(41) * 0.5 - 10.0
x = rebin(v, 41, 41, /sample)
y = rebin(reform(v, 1, 41), 41, 41, /sample)
r = sqrt(x^2 + y^2) + 1.0e-6
z = sin(r) / r

To plot the data as a mesh surface:

surface, z, x, y

To plot the data as a shaded surface:

shade_surf, z, x, y

Therefore IDL is perfectly capable of plotting a surface in one line.

Cheers,
Liam.
