Hugh,
Manipulating 3D data as you say is not simple and will require
preferebly using object graphics or, at least, some creative widget
programming. However, IDL comes with an object graphics demo code called
"surf_track.pro" (in IDL\Examples\Objects directory) that you can call
with your own data set and rotate the 3D model using the mouse:

surf_track, my_z_data

or, to see built-in data, simply type

surf_track

where my_z_data is your own, (regularly spaced) 2D Z-data set. If you
don't get the result you want immediately, at least surf_track will get
you started. You can then modify the data input, include irregular
spacing handling, etc.
Cheers,
Pavel
