Hi Troels,
You are correct that OpenDX is ugly! It's quite old software and it
uses and ancient GUI widget set - Motif. Despite this, the software
is incredibly powerful for visualising optimisation spaces (among
other things). It is especially useful for showing why certain models
or optimisation fails.
Anyway, the way I run this is:
- Run 'dx',
- Click on 'Edit Visual Programs...',
- Select the map.net program created by relax,
- Now I'm getting unrecognised comment errors - strange, I've not seen
that before :S. I'm using OpenDX 4.4.4 for Linux, so that's probably
the difference. Note the files you have attached are not those
directly from relax, you must have saved in your OpenDX version.
- Select the menu entry 'Execute->Execute on change'.
That's it. I now have a 3D frame, but nothing in it. Therefore the
contour levels must be too low or high. From the map file, the values
are in the hundreds of thousands. Then:
- In the main program window, double click on the 'Isosurface elements'.
- Change the values until you see surfaces. In the first the value is
500. I changed this to 500,000.
- In the second, 100 -> 100,000.
- In the third, 20 -> 20,000.
- In the last, 7 -> 7,000.
This should maybe be performed by the dx.map user function,
determining reasonable contour levels, but I have never implemented
this. Anyway, now I have a proper plot. With a bit of zooming,
clicking on 'File -> Save image' in the "Surface" window, "allowing
rendering", and outputting to a large TIFF file, "save current", then
"apply", I have the image cropped and converted to PNG in the GIMP at
https://gna.org/bugs/download.php?file_id=20641. Note that for a good
resolution plot, you will need many more increments. Using the lower
and upper dx.map arguments will be useful to zoom into the space.
Regards,
Edward

Hi Edward.
Can you run this map?
I bought OpenDX (25$) from http://vizsolutions.com/.
And new I have these 4 files.
But the program is maybe the ugliest in the World!
And I don't know how get a image?
Can you run this?
