Perhaps the problem is that the FSC_SURFACE interface doesn't make
explicit how to do it. But I just created what looks to me to be
perfectly acceptable PostScript output by selecting the
Print -> Full Color Printing option and then selecting a
PostScript printer in the Printer dialog, and "Print to File"
option on that Printer. Opening the file in GhostView (I
don't have a PostScript printer on this machine) reveals
a perfectly acceptable (but large) bitmap version of the
graphic. I have every reason to believe it would print in
acceptable resolution.
Perhaps I'll have a few minutes later today to make
this and the vector option to PostScript more explicitly
available in the interface. In the meantime, here is an
article that describes how it can be done in object graphics:

Cheers,
David

I tried the example you suggested...and was very impressed with the cool
interactive twiddling of the surface. For a second I actually caught
myself thinking "maybe I should give up this direct graphics stuff and
check out these object thingies".
And then I had a reality check -- I reckon there's enough insanity getting
my code to display the same on X and postscript...:-)
cheers

You'll need additional functions from David's library:
PickColor
FSC_Droplist
Normalize
All are available from his fine website. Place them in the same
directory as fsc_surface.

You would have to download the whole FSC, or at least all the required
functions / procedures, from David's website.

In direct graphics? No.
In object graphics? Maybe. Try this:
FSC_SURFACE, dist(10), /ELEVATION_SHADING
Then go to the STYLE menu and select "Solid Lego".
The program is here:
