We have an IDL Tutorial

To run the examples - start IDL in this directory.  Then use ".run" to execute
the procedure, e.g.
    % idl
    IDL> .run pro/shade_surf.pro

The workflow examples given in the workshop are:
    sphscan.pro          - generates a .obj file with no color info
    sphscan_intens.pro   - generates an output file suitable for input
                           to OpenGL and OpenSceneGraph examples
    sphscan_mtl.pro      - generates a .obj file which, when taken with
                           an appropraite .mtl file and colormap image
			   can be used to assign vertex color
