== How to ==
* Run 'dx',
* Click on 'Edit Visual Programs...',
* Select the map.net program created by relax,
* Select the menu entry 'Execute->Execute on change'.
That's it.
You now have a 3D frame, but nothing in it. <br>
Therefore the contour levels must be too low or high. <br>
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.
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".
An example image cropped and converted to PNG in the GIMP at <br>
https://gna.org/bugs/download.php?file_id=20641.
Note that for a good resolution plot, you will need many more increments. <br>
Using the lower and upper dx.map arguments will be useful to zoom into the space.
